Car Wont Start

[ibestevo]

Hey guys; So I swapped in a working DOHC engine into my 240. My car is a '89 Fastback base model. Anyway, while I was dropping the DOHC in the car I took off the a/c compressor and swapped in the DOHC ps hardlines. After the engine was in I connected all plugs, connected driveshaft, put in all fluids, and soldered all wires connecting to the ECU. Tried starting the engine and it wouldn't turn over. So I went on nicoclub and went looking for torubleshooting threads. I found one and followed all the procedures. I checked all of the fuel injectors to see if fuel was squirting; works. I checked spark with all wires and all plugs; works. I checked timing as well and that also is not the problem. Those were the three stated procedures to get troubleshooting done. All are not my problem. I have also searched Zilvia's threads for troubleshooting but I had trouble finding any different problems to look for. So if anybody has any ideas I could possibly check to get it running, it will be greatly appreciated. Thanks.

Is there power to the starter?

[ibestevo]

Yeah all three. Cranks like a beast just won't turn over.

Where is the main relay located? And how would I check that?

I think your definition of "turn over" is different than most.

Let me get this straight. The engine will crank (turn over) but it wont start?

If it wont even crank, its a problem with your starting system. Check your starter, relays, fuses etc. relating to that.

Get a chilton manual or a FSM

maby you flooded it

check to see if you gave a ground to your battery terminals, maybe your not getting a reading.

check for vacuum leaks... make sure your o2 is plugged in... take out the plugs and make sure they are clean...

if the starter isnt working check all your starter wiring for shorts, try bypassing the relay/jumping the starter, check your ignition switch, etc.

are you sure timing is fine? alot of people put the distributor in backwards... also make sure you are first priming the system so you are getting fuel..turn key to acessorie turn off....repeat like 3 or 4times
