What’s up guys? So I just purchased a 86 iroc from my neighbor it was sitting in his garage for 15 yrs they bought the house and the previous owner left the car. So it has no title I paid 900 dollars for it. The po ripped the tpi out and threw a carb on it I want to at least try to get the motor running. It turns over but




does not start. It has a torque converter in the back seat so I’m assuming it will need transmission work.

 

Fuel/air, spark, compression. That's all it takes.

Usually, only ONE of The Big Three has gone missing. All you gotta do is, figure out which one it is. EXTREMELY straightforward.

Compression hardly ever "goes away" on its own. Most common cause of that would be the timing chain/sprockets. Ignore that possibility until the very end because it's not near as likely as the others.

Spark can "go away" butt sitting around doesn't inherently cause that. Sure, things can break, and whatnot; butt as a matter of WHAT'S MOST LIKELY, it isn't where I'd start. I'd look elsewhere first.

My first move would be toward fuel/air. OK, I'm betting (perhaps foolishly, butt I think not) that the engine still has access to air. OK then, that leaves FUEL.

Simple. Pour acoupla ounces of gasoline down the carb. Hit the key. If it cranks up and runs for a second or 2 and then dies, BINGO! You have a fuel delivery problem.

Go do the simple and obvious and come back and tell us what happened.

 

My guess is fuel too. There is a fuel filter before the carb and it’s not getting any fuel. I also don’t hear the pump prime when I turn the key on I believe they ran a regulator of some sort but I’m not sure the fuel pump is turning on. This is what is under the car

 

:shrug:

Not too surprised, overall. Regardless, take it one step at a time, and see if pouring fuel into it lets it start. Logic. Reason. Process.

 

I don't know how these things are handled in Texas, but, if I were in your situation the first thing I'd be doing would be finding out what it's gonna take to get the car legally in your name, before spending anymore $$$ on it.

Where I live it's a downright PIA to re title an abandoned car. It can be done, just gotta jump through the RMV hoops....

 

The title is clean it was just lost basically. I ran a vin check on the car before purchasing it.

 

Bingo poured some gas in the carb and it started right up but died. I have to figure out what the previous owner did. I know for a fact the fuel pump is not engaging when the key is turned. So I will have to see what was done

 

Hard to know whether there's still a fuel pump in the tank or not. I'm gonna guess, not, though; that little lawn mower thing on it now, with the 1/8" pipe fittings and the crimped rubber hose, can't possibly draw through a real pump, can't possibly deliver enough fuel to run a car engine anyway, and that low-pressure cheeeep fuel/vacuum hose wouldn't withstand the pressure that the original pump would have generated. I can't imagine that the car ever "drove" like that; looks almost kinda more like a mere "demonstration" of being able to start it at one time, than anything useful.

Put an actual automotive fuel pump on it, with non-fire-hazard plumbing of some sort. Check for 12V on the red wire leading to that little bitty thing when it's supposed to be there. Look carefully at that wire and see to it that it's big enough to carry the current that a car fuel pump will require. Then of course, assure that power is fed at the right times; an ideal situation would be for it to prime for a few seconds when the key is first turned, then for it to get power only when there's oil pressure. Or, if the original pump is still there, you could maybe figure out how to use that, and use a 3-port regulator (high-pressure in, low-pressure out, return to tank) to knock the EFI pressure down to 5 psi or so.

 

That’s what I was hoping that they left the pump in the tank and ran a regulator but I will have to check it maybe I can find the wires to the original fuel pump and run power to it and see if it turns on. Maybe they left it in there.
