twind Posted May 10, 2005 Report Share Posted May 10, 2005 I have 90 regal. I put a 3100 out of a 95 lumina. it ran fine for a week or so then started idial high even low. now it will not start, but fires. i've changed the coil packs, cps, ecm, fuel pump, filter. it get fuel, but will not start. you can here the injectors come on then when the injectors shut off you can hear knocking. any ideas Quote Link to comment Share on other sites More sharing options...
Baddflash Posted May 10, 2005 Report Share Posted May 10, 2005 What electronics/injectors are you running, from what car? Quote Link to comment Share on other sites More sharing options...
twind Posted May 10, 2005 Author Report Share Posted May 10, 2005 the only thing that was changed was the injectors from the regal. everthing else adabted. the ecm from the regal. the engine from the lumina and everything that was on the engine was used.

Canada Posted May 10, 2005 Report Share Posted May 10, 2005 I'd check compression. Quote Link to comment Share on other sites More sharing options...
twind Posted May 10, 2005 Author Report Share Posted May 10, 2005 it will run for about a day, then it will die start then finaaly not run at all,but will turn over. Quote Link to comment Share on other sites More sharing options...
Canada Posted May 10, 2005 Report Share Posted May 10, 2005 So....right now.....it won't start no matter the day of the week? Â Check compression and spark (get a spark tester...don't just hold a plug against the block)......also...check over your work. Make sure you got the correct wires to the right cylinders. Â Â Â I should also ask....this car doesn't have an aftermarket security alarm...does it? Quote Link to comment Share on other sites More sharing options...
twind Posted May 10, 2005 Author Report Share Posted May 10, 2005 it's got spark. no security alarm. it's got good compression Quote Link to comment Share on other sites More sharing options...
Canada Posted May 10, 2005 Report Share Posted May 10, 2005 What was the psi? Â What was your fuel pressure? Â Correct spark.....on all cylinders? Quote Link to comment Share on other sites More sharing options...
twind Posted May 11, 2005 Author Report Share Posted May 11, 2005 if the fuel pressure, and compression is good what else could cause this a shorted injector? but would it still fire? Quote Link to comment Share on other sites More sharing options...
twind Posted May 12, 2005 Author Report Share Posted May 12, 2005 Is there a wat to bypass the crank sensor. I have no spark right now. I just want to know if the sensor before i have to spend any $$$$ Quote Link to comment Share on other sites More sharing options...
sonyman87 Posted May 12, 2005 Report Share Posted May 12, 2005 crank snesors arent expensive are they? Quote Link to comment Share on other sites More sharing options...
twind Posted May 14, 2005 Author Report Share Posted May 14, 2005 Not really, but i did want to spend it if i did not have to, i did still no go. I repalced the harness that connects to injectors, alt, map, iac, temp. The car fired before i changed this harness. now it will not even fire. the old harness had exposed wires and broken ones also. the harness came off a olds with 3.1. it was a little differnt like one alt wire instead two that were on the alt. the CPS wire was not in there, i had to pull it out. the pin outs are a little different like 4 or the color code is complely different. is there any thing else that controls the spark. i have changed ecm the coils, ignition module,fuel pump. you can here the injectors come on. i don't know what else to check Quote Link to comment Share on other sites More sharing options...
