S10 Cranking problems-please help.

[Fubz]

1989 Chevrolet S10 2.8



Problem:

While running a power wire to a hot point on the firewall I forgot to disconnect the battery and caused the metal wrench to ground out and arc against the air filter for about 3-5 seconds. After that the truck will turn over but will not stay cranked. Here is a picture of what the "thing" looked like that I attached a wrench to:



Here is what we have concluded/theorized/tested/havenotcluewhatwearedoing/:

1. All fuses have been checked and are not blown. All fuse holders have been tested for power and they are ok. This was tester using a light tester. Here is a picture of the fuse box under the steering wheel.





2. If we remove the air filter and put gas strait into the intake it will sputter like it wants to keep going then just dies as soon as all the fuel that was poured into them has evaporated.

3. When ignition is turned on the fuel pump does not click on.

4. To test to see if the fuel pump will power on at all we ran a temp wire from the battery strait to the fuel pump. I think this bypasses some relay that I have yet to locate. When this test is done the fuel pump does power up. The positive cable running back to the fuel pump is Red and the other cable was brown the ground.

5. To test to see if we were getting gas flow, we removed one of the fuel lines from the fuel injectors and briefly powered up the fuel pump as mentioned above. Gas was pumped out.

We are kind of stuck at this point...



1. How do we check/test the fuel injectors.

2. During my hours of reading to fix the problem I see people mention EGR Valve, could this be the cause of the problem or is it totally irrelevant? Where is this Valve located, what purpose does it serve?

3. Is there anyways we can check the computer?



Here are some pictures of my engine and anything I think could be relevant

Thanks in advance for any help or advice you can lend. This is the only automobile I have and I really cannot afford to take it to a shop until I have exhausted all other options.

the fuel pump relay is in the engine compartment on the firewall. its on the back corner on drivers side. a little black cube. if you have a cluch, its to the left of the cluch fluid resivior. replase that and ckeck all grounds including the ground to the pump.

the egr is not your prblem, but it is behind the throttle body and just under the fuel lines.

Check your fuse box again for the ECM FUSE or ECMB FUSE. I had the same thing happen to me also. I thought mine were ok but i checked a 2nd time and i was wrong. I hope you find the problem
