I just installed a motor in a 91 N/A. It will only fire for a seconf and then stops. I checked the intake and the plug was connected, so I checked to see if it was getting fuel. I know the pump is working and going through the filter, but it will not stay running. It had some bad gas in it, so I am wondering if the fuel injectors could be plugged. Anyone run into and issue like this, or have any ideas?

so does it actually run or just make a sound like its running for a second?
you need 3 things - fuel, ignition, and compression. if you have all three then you start focusing at vacuum/intake leaks, loose/misplaced wires bla bla bla. also check your timing, very important. kevin. |
It actually starts, but only for a second and then it dies. I replaced all of the vacuum lines and checked them for leaks again. I am getting fuel up into the rats nest, but I still need to check the pressure. The timing is good. Compression is good. I have checked for every loose wire possible, and then added an additional ground on. I am going to check the fuel pressure and then check the injectors.

yea my next step would be hecking the fuel pressure.
you do have a strong spark right? stock coils? oh and make sure you dont have the leading and trailing wires messed up, itll cause similar symptoms. remember trailing is on top. kevin. |

Have you checked to see if AFM is working properly?

OK, I pulled the fuel pump back out because a friend that was helping me said he did not put back in a little white spacer. Anyone know where this spacer fits? Does it go between the pump and the tube going to the engine or before that? It is a small white plastic washer. Any help would be appreciated.
