No run. Had to tow home.

[Fox Slaughter]

Well I went to Napa and on there I got on it at a light car just dies, I pull over car starts right back up. Get to Napa get my filter then go to leave car won't start.

I noticed I burned two of my spark plug wires on the headers, so I pushed them away so they weren't touching anymore. They burned the covering. Kept trying the car started once and then stalled out. I borrowed some ether and a screw driver from Napa. The car started on ether. Pushed the fuel valve on the fuel rail fuel came out.

Got the car towed home, put on my fuel pressure gauges, reads around 40 psi even when cranking. So I had my buddy crank and I sprayed ether constantly into the throttle body. Can ran rough but she ran, he said the SES code was on, so now I have to wait till my buddy gets off work with his fancy 2000 dollar scanner because at Autozone it wouldn't pull the codes.

Any idea? Possibly weak spark? I replaced the MSD coil with just a Duralast one because the MSD coil went bad.


I have never had any of my cars on a flat bed before

better get used to it if you want to mod your car... mine was flat bedded or trailered home more time last year then i drove it back home..

Replace the wires and go from there. Are you running open headers at this point? That would do it for sure. Autozone won't be able to read that car because it is an obd 1.5 car. Whatever you do, don't let anyone stick pins in the obd port.

[Fox Slaughter]

Yeah I still have the stock wires sitting in my garage I am going to slap those back on. My buddy's scanner reads the OBD 1.5. I don't get how the wires though will allow the car to run on ether but not on fuel.

As far as open headers I have at least a 1ft and a 1/2 of pipe coming off the headers as my neighbor hasn't had free time to tig my exhaust and I've been lacking motivation to finish fitting the exhaust.

[my95z28]

Completly agree, but that is the first place I would start since they need to be replaced anyway. it does sound like a fuel problem though. The fuel pump was replaced at 65k miles, but it could have went again, thay are notorious for being finicky. have you ever ran the car out of gas? below 1/4 tank is really bad on them because the fuel actually cools the pump.

[Fox Slaughter]

The car has ran past 1/4 usually if I cruise I use a 1/4 for weight reduction haha. I hope its not the fuel pump cause I am not doing the trap door method.

[SoulTerror]

Must be a bad day for Fbodies. Mine lost third gear today.

Good luck on getting it going.

[meissen]

If the fuel pump was going, you wouldn't have 40psi at crank... I'd think it's either the wires or the optispark.. especially when you say you were getting on it when it happened.

[Fox Slaughter]

Well when I had it running on ether constantly spraying ether in a SES code popped up so I am waiting for my buddy to come over and scan the code. I looked at the wires that were burned. They just changed from red to white, can't see any internals or anything. The coating is cracked though. Could it be the Duralast coil gone again?

Could it be providing enough spark to ignite ether and not the fuel?

Fuel pressure: ~39psi
Crank Fuel pressure: ~38psi.

Popped off and injector real quick checked resistance it was within specs for ohms.
Checked the connector got 11.87v.

[jakes_GSXR]

ive got 60 psi of fuel pressure

[Fox Slaughter]

ive got 60 psi of fuel pressure

Chiltons says between 41 - 47psi.

"2) With the key ON & engine OFF (cycle the key ON-OFF several times as pump only runs for 2 seconds) the pressure should be 41-47 PSI. (If NOT: weak pump, dead pump, or no power to pump)" from another Forum.

So does it sound like its the fuel pump again?

Looking over the records. Kyle this says you had the fuel pump changed at Carron Chevy 4/25/2008 at 57,670 miles.

Also after letting the gauge stay attached the fuel pressure has dropped at least by 3 - 4 psi. So the fuel pump is not maintaining pressure. So the internal check valve on the pump is bad?

[jakes_GSXR]

dude, if i were you, id change those wires out. i burnt ONE wire and my v8 was running like changed the wire and fixed it.

but it always runs like shit anyways so..

[my95z28]

The check valve is actually exactly what was wrong with my car. When it went bad on le it would take 4-5 seconds to start, bit once started it ran great. Sorry, couldn't remember the actual mileage I did the pump at, you have all the records now. And caron only diagnosed it, I put the pump in.


Oh yea, if you are scared of cutting the car up to do the pump, don't be, I already did it for you

[Fox Slaughter]

Haha you already did the trap door method? Because no codes were on the PCM. My friend watched the gauge my mechanic friend when it primes it goes to 39psi when I crank it drops to 36psi then back up to 39psi when I let off.

So did you just cut 3 sides and bend the floor up and just push it back down or did you like tac weld it back shut.

[jakes_GSXR]

sounds like your fuels fine.
