I have a 96 Silverado that won't start

There are no codes and if it is the timing how would I fix that It did say in the computer that spark advance was at -30 that can be changed on the distributor but is timing that easy?

I'll test the compression and I'll see where it goes from there

OK I just tested compression and it showed 180 psi I put a new coil on last night does it have to be connected to the bracket for it to be grounded out and work right? And how do I do what you mententioned about the TDC #1?

I'm just curious to know...did you get the truck going?? I'm having the same issues with my 96

No I didn't I traced it down to the pump...I'm only getting 9 volts to the plug on the pump when I should be getting 12. I replaced the relay showed same volts. What could cause this to drop volts in the circuit after the relay?

The plugs are new and we cleaned them. I had a buddy come over yesterday and he did a bunch of tests and he sprayed starting fluid into the throttle body and it fired right up and ran fine but when I would give it gas it bogged down. Its because there's not enough power to the pump but I've traced it past the relay and there's 12 volts until the wire goes into a box on the firewall and I don't know where it it goes from there. I need to know how the wiring from the the battery to the pump works.

Where is that?

OK and what about the grey wire. How many volts should that carry with the key on?

There a grey wire going to the fuel pump it would be a lot easier if you text me and a lot quicker I need to get it done as soon as possible. You can text me at 501-270-0207

Change your distributor

Okay my truck is fixed!!! It was distributor cap and rotor. The vent underneath was clogged with gunk so the poor thing couldn't breathe! Thanks for all answers Suzanne
