LW300 not starting after engine swap?

[danielgluch]

Hi guys, I'm new here. My names Daniel.

I have a 01 LW300 V6 which I just swapped the engine due to timing belt breaking, now no start no crank.
No fuel pressure at rail and no 12 volts at starter or park/nuetral safety switch. Ignition key is missing key fob remote. Any ideas??


Thanks in advance
Daniel

1-Did you check every wire harness during the engine swap, battery connections, all engine/chassis grounds? Checked for blown fuses in all three fuse panel locations?

2-Can you hear the faint hum/hiss sounds of the pump running for 2 seconds when ignition is first turned on? Depressing the fuel test valve is another way to see if fuel pressure develops when a pump runs. Saturn fuel pumps do not run continuously with ignition ON engine OFF. Starting allows the EFI system to turn on pump operation.

yes, but one i cant find it is a male two prong connector with a purple and yellow wire, it only has one inch of slack off the harness its right on the trans near the connectors for the coil packs. It has 5 volts when the key is on. Any ideas?

No all I hear is the throttle body

[fdryer]

The throttle body enters an automatic calibration mode (slight whir) after ign is left ON (engine off) beyond 30 seconds.

Here are two drawings with the same yw/ppl wires but different plugs.

Ya it s the throttle body making noise.
The connector is right where the trans and engine meet under the manifold. Im baffled, it right near the water distribution pipe??

Did you mouse over each thumbnail and click on it to open a larger view of the two connectors?

[danielgluch]

Yes it does not look like either of them

is the crank sensor plugged in????they tend to flop down and be missed.. this moter will run with out a cam sensor but won't fire without crank signal..

[danielgluch]

crank pos sensor is plugged in, im gonna try old crank sensor see if it works.

Problem finally solved.

Signal wire from the alternator that send voltage to starter solenoid was damaged, I replaced the wire and fusible link and starts like normal.

Thank you all for your help

Remember to always check the basics first.
