i have a 89 ef hatch with gsr swap, engine will start and run on like 1 cylinder. running obd1 injector and ecu, i didn't relize i didn't have to run the resistor box, and run with box a long time, the box is toast, i cut the wires and put them together. i ran a good ecu, dizzy, injectors, and a good main relay, still will not start up right, and u have to push the gas pedal down to keep it running. i haven't try fuel pressure regulator yet, but anyone come across problem before can give me some info.

 

firing order right? its suprisingly easy to mess this up lol

cel on? if so have you figured out what codes you have?

 

this happened to me a couple months ago. i had replaced nearly everything until i finally blew out my fuel lines and they where clogged with gunk. just an idea.

 

sounds like you messed up ur fiting order..in the faq there's a diagram on obd0-obd1 conversion.i used it for my swap and I never had any of these problems.

 

is not firing order, really is my friend car that i helping him to get it running, i find out few problem. one was out of time by 2 teeth, second the obd0-1 jumper was bad, after fix both, it ran better, so did compresson test. gsr with type r piston bore 81.5, mill head, it was pulling 250 on 1, 210 on 2, 270 on 3, 260 on 4. did a leak down, almost broke the needle on 1, assuming 400, 270 on 2, 350 on 3, 360 on 4. so i assuming rings no good and also either carbon build on valve or bend valve. the motor only 8months old, not even 6000 miles on it. i tried to help him explain that possible rings and something going on with the valves, he ask the machine that build his motor(along 3 other they build for him that blew up, and they are dirt track race car building...) they said that with that much compresson that he be 14:1 and that he should ran alchol, and thats why he blew his motor, and also his compresson gauage is wrong. i told him, it doesn't matter u read 100psi or 1000 psi, if gauage is wrong, it wouldn't make your number 2 over 20 of a different then any other cyclinder. any of you guys know wheres a compresson table online somewhere so i can show him what i talking about. thx

 

So he drove it 6000 miles without a problem, and now it's having issues?

Can you hear where the air is escaping from with your leak down test?
