Symptom
Poor idle speed, malfunction etc
Symptom
Fail to start5-125 Repair precautions:
1. according to engine requirement, electric fuel pumps with different flows are available, they have the same
appearance, mountable fuel pump may not be exactly suitable, during repair, part number of fuel pump used must
be consistent with original one, wrong replacement is not permitted;
2. in order to prevent fuel pump from damaging, please do not run it in dry state for a long time;
3. in case fuel pump needs to be replaced, please pay attention to clean fuel tank and pipeline and replace fuel
filter.
(2) Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect two meter pens with fuel pump pins
respectively, measure internal resistance, it should not be zero or infinite (namely not in short circuit, open circuit
condition).
(Connect joint) connect fuel pressure gauge on sucker, start up engine, run the engine at idle speed, now fuel
pressure of engine should be about 260kPa; unplug fuel pressure regulator vacuum tube, now fuel pressure should
be about 300KPa.
11. Canister control valve
(1) Canister in fuel evaporation control system adsorbs oil vapor from oil tank until saturated. Electronic
control unit controls opening of canister control valve, fresh air and saturated fuel vapor in canister form
regeneration stream, which is led into engine intake pipe again. Electronic control unit changes duty ratio of pulsing
signal to canister control valve solenoid according to different operating conditions of engine, thus controls flow
of regeneration stream. In addition, this flow is also influenced by pressure difference at both ends.
Possible cause
Entering of foreign matter into valve inside results in
corrosion or poor leak tightness etc
Repair precautions:
1. To install, airflow direction must meet the specification;
2. when black granules inside valve body result in malfunction of control valve, and control valve needs to be
replaced, please check the condition of canister;
3. avoid water, oil etc liquids from entering valve as far as possible during repair;
4. in order to avoid transfer of solid-borne noise, it is recommended to install canister control valve suspending
on the hose or use soft rubber to fix.
(2) Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect two meter pens with canister control valve pins
respectively, rated resistance at 20°C is 22 - 30 ohm.
12. Ignition coil
(1) When earthing channel of primary winding is connected, this primary winding is charged. Once ECU cut
off primary winding circuit, charging stops, high voltage is induced in secondary winding at the same time, so spark
plug discharges. Ignition coil ZSK 22 (both ends of 2 secondary windings are connected with a spark plug
respectively, so these two spark plugs ignite simultaneously.
Possible cause
Too heavy current leads to burnout, damaged by external force Repair precautions: it is prohibited to use "short circuit ignition testing method" to test ignition function, soEngine EFI System-

Repair precautions:
1. Don't remove ECU at discretion during repair;
2. ECU may be removed more than 1 minute after removing storage battery head;
3. Store removed ECU properly;
4. It is prohibited to attach any circuit onto connecting wire of ECU.
Simple measuring method:
1. (Connect joint) use engine data K-line to read engine trouble record;
2. (Remove joint) check whether ECU connecting wire is in good condition or not, mainly check whether ECU
power supply grounded circuit is normal or not;
3. Check whether external sensor works normally, whether output signal is credible, whether circuit is in good
condition;
4. Check whether actuator works normally, whether its circuit is in good condition;
5. Finally replace ECU to conduct test.

(f). Flatten the edge with hammer or sizing block, and remove the burr with file to make sure that it is aligned
with the both side alternative plates with a clearance not more than 1mm;
(g). Replace the plate, and clamp it with pincers. Carry out the spot welding along the seam at a space of
approximately 50mm;
(h). Make the welding from the center to both sides alternately block by block. Which can reduce the
deformation;
(i). Strike the welding line with the hammer or sizing block to remove the retaining stress. Polish the welding
lien wit the file or manual grinding wheel to make it even and smooth for the painting.
c. Repair for Accidented Damage
(a). Plate work flattening
When the accidented damage occurs on the plate work of the body, it can be repaired by means of beating.
In the repair process, start from Point C as shown in Fig. 5-26. Put the sizing block on the convex point, and beat
it with the hammer and change the block's position correspondingly. When the convex point is flattened, the
concaved part in Point B will rise. Similar wit the original profile of the plate, for the remaining dent, a sizing block
with the same radian can be employed. Press the bottom of the plate with hand, and beat the high point of the dent
with the hammer. (Fig. 5-27)Fig. 5-27 Plate Work Flattening (II)

Convex Point
1. Heating pointBody Repair -Repair After Body Damage7-19 In the beating process, beat the work piece heavily at the beginning and lightly at the end. Attention shall
be paid to reduce the number of beating as possible as it can. Don't beat the same points repeatedly to prevent the
metal plate extending locally, which can complicate the repair work.
For the larger arc concave, a sizing block can be used under the center of the concave. The area of the sizing
block shall be a little larger. Jack the concaved plate up with a supporting tool. Sometime, heat the concaved part
to wine color to reduce the force. When jacking the plate up, a little excess is acceptable. (Fig. 5-28)
(b) Thermal contraction
When the concave is jacked up, if the plate extends seriously and the area is large, the thermal contraction
method can be used in case that the traditional methods don't work. (Fig. 5-29)
Heat the work piece to cerise color with oxyacetylene flame. The heating scope depends on the degree of extension.
If the extension is serious or the area is large, the heating point shall be larger relatively (diameter: approx.20-
30mm). If the extension is not serious or the area is small, the heating point shall be a little smaller (diameter:
approx.10-15mm). After the heating, beat the heating point immediately. In the beating process, a proper sizing
block is used under the plate. After it is cooled down, beat it lightly with the hammer.
The contraction starts from the highest point to the center, and then to the edge. Heat and flatten the extended
part repeatedly till the plate is flattened fully. If the convex part is too high, compress it to one half of the original
height. After it is cooled down, heat it at the original heating point till the other half of convex part is removed.

7-35Section 5 Painting Techniques After Body RepairIn the practical use, various factors may cause painting damage, such as traffic accident, component rust,
premature damage due to bubble, and local color change etc. It is necessary to make repair locally as the following
steps:I. Base Processing (Pretreatment)1. Remove the paint, and remove the coating on the plate work.
2. Cut the edges and corners, and polish the metal plate without paint and the uneven paint at the edge.
3. Blow and clean the dust and dirt, and remove the grease with degreasant.II. Primer Processing1. Apply the self-drying primer on the bare metal surface.
2. Leave the primer drying naturally, or dry it with the infrared radiator.
3. Apply the self-drying oily putty or polyester putty on the plate work surface.
4. Leave the putty drying naturally or artificially.
5. Polish the putty manually to remove the uneven parts.
6. Polish it manually in water to clear the sandpaper lines.
7. Wash the dirt, polish the oil dirt and putty slurry.
8. Wipe the oil dirt on the polishing surface.
9. Cover the part not to be repaired with protective shield or paper.III. Painting Intermediate Coat1. Paint the second primer.
2. Leave the primer drying naturally or dry it.
3. Find out the sand hole or sandpaper line.
4. Polish it manually in wet condition.
5. Wash the part clean, and leave it drying naturally. (The number of putty applying and polishing depends on the
evenness of the surface to be repaired.)IV. Preparing to Paint Surface Paint1. Paste paper on the surface not to be painted.
2. Remove the dust and grease on the local surface paint.
3. Mix the color the same with that of the vehicle's surface paint.
4. Prepare the paint.V. Painting Surface Paint1. Paint the part with fast-drying surface paint 3-4 times and synthetic resin paint 2-3 times.
2. Leave it drying naturally or dry it.VI. Polishing1. After painting, burnish the part with wax to clear the shadow and improve the effect.
2. After painting, tear off the paper and wipe the ground paint.
3. Check the appearance and quality.Body Repair -Painting Techniques After Body Repair
