GOTHALOSISM Posted January 11, 2011 Share Posted January 11, 2011 Well I have an interesting dilema that I would like to hear your inputs on. I have not been able to get my LT1 to run (injectors are not firing), I have trouble shot it down to either the PCM or the EProm chip. Now My wife wants me to get the car out of the garage and get it running. I put the engine on CL in the barter section. I was asking if any one wanted to trade my LT1 for a Carb'd 350. I had a guy call me saying he just pulled a 350 bored to a 383 stroker. He wants the LT1 for his 36 chevy. The 383 came out of a 94 chevy truck, the engine was rebuilt with forged internals back in 2007 and pretty much just sat there for the past 4 years (lost title to truck and they burnt the tranny (th400). He also said he has all sorts of intakes and carbs to pick from. So if I do decide to swap the guy what intake should I look for and what carb? I was thinking a 600 quad but not sure if that will be to much. Thanks Quote Link to comment Share on other sites More sharing options...
jasper Posted January 11, 2011 Share Posted January 11, 2011 (edited) My opinion....get some professional help (automotive ), and keep the LT1. Computors are cheap, and you may also have a very simple problem. Just my 2 cents...... Edited January 11, 2011 by jasper Quote Link to comment Share on other sites More sharing options...
GOTHALOSISM Posted January 11, 2011 Author Share Posted January 11, 2011 I had a friend come over with an odb1 scanner and even it would not link up to the PCM. We tested everything that we could think of. with it being a 93 ecu I could not just swap out the ecu. Quote Link to comment Share on other sites More sharing options...
jasper Posted January 11, 2011 Share Posted January 11, 2011 (edited) On some systems, if you don't have a check engine light lite up with key on, You WILL NOT be able to communicate with the ECM. Something as simple as a blown check engine light bulb can prevent scanner communication with the ecm. What about a FACTORY service manual diagnostics flow chart???

GOTHALOSISM Posted January 12, 2011 Author Share Posted January 12, 2011 I'm running a standalone harness with the check engine light witht he fuses. It won't even blink when trying the "paperclip" trick. Quote Link to comment Share on other sites More sharing options...
jasper Posted January 12, 2011 Share Posted January 12, 2011 Is the bulb good??? Quote Link to comment Share on other sites More sharing options...
GOTHALOSISM Posted January 12, 2011 Author Share Posted January 12, 2011 oh yeah bulb wont go out... I just downloaded a full re-wire step through for this harness. If after I get it rewired from scratch if it still does not work i'll go with the 383. Quote Link to comment Share on other sites More sharing options...
hoov100 Posted January 12, 2011 Share Posted January 12, 2011 Why not just convert the lt1 to a carb setup if you can't get the EFI system to work? Quote Link to comment Share on other sites More sharing options...
GOTHALOSISM Posted January 12, 2011 Author Share Posted January 12, 2011 can't afford the intake/carb, dizzy right now. If i have to swap i get everything for free. Quote Link to comment Share on other sites More sharing options...
GOTHALOSISM Posted January 13, 2011 Author Share Posted January 13, 2011 Found out the ECU is bad, going to try to find one locally, if not send mine in to get replaced/repaired with the eprom reflashed. If I can't get it running correctly by feb 1st then on to the 383 swap. Quote Link to comment Share on other sites More sharing options...
rsicard Posted January 13, 2011 Share Posted January 13, 2011 Found out the ECU is bad, going to try to find one locally, if not send mine in to get replaced/repaired with the eprom reflashed. If I can't get it running correctly by feb 1st then on to the 383 swap. With a good ECU, wiring harness, Optispark, fuel pump, fuel pressure regulator and plug wires everything should be a GO. MSD makes a VERY GOOD replacement for the Opti-Spark much better than the originals. 1994, 1995 were OBDI wheras 1996 was OBDII and much more complicated.

GOTHALOSISM Posted January 13, 2011 Author Share Posted January 13, 2011 Yeah the 95+ have the vented ones and require vaccuum from the intake. If I could afford it I would just go Megasquirt with ford edis-8 Quote Link to comment Share on other sites More sharing options...
