Default Car

Thank you Guys for the feedback. You are the experts.

Remember that I bought this car with missing parts. :[

1. Car is not coughing or sending smoke out of the exhaust.

2. There are two blue wires left. Possibly for the egr that its not present.

3. I just bled the whole system; still no start.

4. The two wires to the IP:
One is yellow and the other blue.
The way they are setup (yellow) is not giving 12v to the upper plug (fuel solenoid); but is giving (blue) 12v to the bottom plug (altitude).
If I switch them (yellow and blue), the car does not crank at all. :[
If I set a 12v jumper to the fuel solenoid, the car will not start. :{

5. Car was timed properly. Removed the valve cover to set cam lobes in piston one to horizontal, and the little 0 set on the flywheel.

6. Pump was set to .085 degrees.

What do you mean by "bled the whole system." Did it include bleeding the injector hard lines?

So those wires are probably not the correct ones. Find the ones that behave as explained in post #7 above.

You stated new GPs but are they all getting +12VDC during the glow period?

Have you studied the Hard Starting sticky?

Yes. The whole system. Includes the injectors hard lines. Used a syphom pump to get it done.

GP's are getting their 12v. System is working fine.

The two blue wires (they send 12v with the switch on). If I used them instead the other two (yellow/blue) a short circuit cut the whole system. I turn the key to on and no lights/cranking happens.

The shutoff solenoid was not clicking. I put it apart, cleaned up. Now is clicking.

Will continue tomorrow.

Thanks for all the feedback.

I am going to start this bad boy. Its mad at me.......

Looks like you have a wiring problem. You will have to work around it in order to get the car started ASAP, so just hotwire the fuel shutoff solenoid for now w/ +12VDC. You really don't need anything more than that. Fuel, good cranking speed, glowplugs, compression-- that's it!

Hold the throttle wide open when attempting to start, and verify you have fuel dripping from loosened injector line nuts at the injectors during cranking. If not, the car will not start. (You must retighten the injector lines to the injectors after verifying fuel is being sent to the injectors. 18 ft-lbs. means do not overtighten.)

PS: Can you describe how you bled the injector hardlines with the siphon pump? Curious to maybe find out a new method.

Timed the car again.
TDC . Pump to .087
Car is coughing.
Found out problems with the within harness connections closer to the go relay.
Will fix problems.
Sometimes car does nor crank at all and the 12 volts to up solenoids cut off.
More to follow.

Resending due to typos.

Timed the car again.
TDC and camshaft re-check.
IP to .087
Car is coughing. Almost started. Then quit overall. No cranking.
Found out problems with the wiring harness connections closer to the glow plug relay.
Will fix problems.
Sometimes car does not crank at all, and the 12 volts to injection pump solenoids cuts off.

More to follow.

Talking Wiring harness

Working on the wiring harness.
Some cables got loose and do not know the arrangement. Please help.

The first one is the relay located next to the glow plugs relay. It is a 4-prongs plug. The female plug is broke and have cables loose. Colors are yellow, blue, green, black. See pic of the relay.

The other plug is in the same area. This one is flat 3-prongs. Two wires are beige and the other one is yellow. One of the wires connect to the relay above. Need to know which one is, and where the other two connect.

Would apreciate that any of you send me pics of both plugs to determine the arrangement.

Car is alnost ready to start.
