thanks guys a friend of mine loaned me an injector today. so I will switch it out to see if it still does it tomorrow. I have not done a compression test because the motor has less than a l000 miles. I will get around to compression as last resort. THanks for responses all you guys have been...

only the number 6 cylinder plug is soaked. and fuel is on top of the piston

Well I have to work on the car by myself alot so nobody to watch the plug. but I did put a spark plug light into the #6 coil wire and spun the engine over. The spark light was very active. Now I can cant spark on the plug. But I bought new plugs before i started yesterday. they shouldnt file...

yes supra guy I check the injector plugs 5 and 6 cylinders were switched. The car did crank up better and quicker and it did not backfire. but its still overfueling. THis is what I did. Right after It ran for like 15 secs before flooding out, I immediately took out all spark plugs to look off...

jay thanks I will be hitting you up if I need any 7m parts. thanks for the offer. You and these guys on this forum are just awesome.!!!!!!!!

first of all thanks for the response. But I really hope you are wrong about my issue lol... no disrespect though. I will let you know , although you maybe right I still think it is a major overfueling issue when injector 5 and 6 are switched. I atleast will have to look into it. Thanks.

hey after church today, I will get right on it and report back as soon as possible. although after the post I just got from jg5899 it does not sound to promising. jg5899 just said the he mixed up 3 injectors and his car started and ran fine. I only had two and mine wont rev up and runs like its...

THanks for your response Indigo but we said the exact same thing a different way. I just gave the color of the second wire. I just thought it was understood about the yellow black white wires. sorry my fault on not being clear. 2. come to find out cylinder 5 and 6 injector wires were switched...

No i have not. I am not immune to simple mistakes as that. I label all electronic parts with tabs upon dissembly to prevent this. I will have to check again because I have tried everything else. I just check the TEWD. It was kind of confusing, It didnt have the injectors in order. This the color...

The engine was fully rebuilt and machined head and block by a guy who owns a rail and has his own machine shop. The engine was blueprinted and balanced internallly. the front cover was machined with the block. I also checked the rivets before putting the head on the block. the new cometic...

Thank you for explaining that. I did solder new injector wire onto the factory harness to make the rc 550 fit. but i did that years ago the car has been running fine up until this last rebuild. But Either way thanks for your response and this week I will check them out.

I will check that. I will have to look at tsrm because I am not well versed in wiring. Other than the color scheme I am lost that will be a hard job but has to be done. Can please explain why crossed up wiring causes overfueling? I just want to know why. thanks for the response

yes. the j tube is removed. the egr is removed. the fuel pressure is set as low as it can go the screw is almost out. the guage still reads 20 psi while cranking. thats with vacuum line connected. I also have the driftmotion upgraded ss return line.

I dont post alot because I really try to research before I post a question. I have a rebuilt 1990 7mgte with less than a 1000 miles. Mods: lex afm/ rc550/walbro gs315/aeromotive fpr. Issue: car was running great after rebuild but i blew the headgasket within 600 miles. took bad advice and used a...

I had that the exact same issue with an upgraded ct-26 60-1. I had 3 things going on so I dont know which one it was. But had a code 52 which retarded the timing, exhaust manifold leak, busted intercooler cooupling(boostleak).

I had that problem. The wires help alot, using copper plugs helped alot and gapping to about .025. if that doesnt work, look at your coil packs if they cracks in them you may need to replace them... It cured my problem. They were expensive so exhaust all other options first.
