    1987 Chevy 305 TBI Hard to start after warmed up.

    Re: 1987 Chevy 305 TBI Hard to start after warmed up. Alive Again It's alive again. Control module was problem. I still can't see how it would run with bad control module.

    Cleaned up ground next to Temp sensor. I then checked to see if I was getting fire to the computer (already had it out). Just checked with test light not meter. with the key in on position I checked the smaller plug (closer to seat) first. I had fire in some of the plugs but when I stuck the...

    Thanks for reply Transman. I have two relays on firewall. I think the one closer to driver side is for the trans (TH400) that what the book says. The relay on the passenger side has red wire hanging out. That is what I have been using as a test point. The fuel pump only had rubber hose and...

    Hello Transman, Sorry for time in between posts I only have weekend to worK on it. Somehow this post got moved from another subject post of mine. The hard to start when hot is not the problem. It will not start at all. No fuel pressure. I have checked the grounds- even added ground near tank...

    1987 Chevy 305 TBI Hard to start after warmed up.

    Checked control module. It checked bad. Replaced - still will not run. When I hook a test light to the test lead from the relay - turn the key no light. start cranking - no light. As soon as I stop cranking the engine the relay clicks the test light comes on for about five seconds and then goes...

    Fuel Delivery Problem 87 Chevy 305 TBI

    Sorry long time since last post. Just found that this thing has 2 oil pressure sending units (one at distributor and one @ #7 cylinder). I am still going to check the voltage at the tank connection first before anything else is replaced.

    Fuel Delivery Problem 87 Chevy 305 TBI

    Gus, I rechecked the connection. It had a bright light-must of had not too good ground. Went to pull tank this morning and found that the damn thing was leaking. I had replaced the tank about 10 years ago because of the same kind of leak. Must have been the rust and dirt holding the gas in and...

    Fuel Delivery Problem 87 Chevy 305 TBI

    So if I have the tank out I should be able to run a wire straight from battery and ground the ground the pump should come on? I had hot wire all the way to the elec connection @ tank in and out. Messing with the ground and broke the end off, so I have to take out tank to fix ground.

    Fuel Delivery Problem 87 Chevy 305 TBI

    Replaced pump last night made sure ground was good and checked elec connector at tank. Nothing changed. I hooked a jumper to test lead and pump does not come on. I put a test light on the elec connector at tank and got a dim light.
