this could be a bad conector, wire, or your timing is just off. Jiggle the CPS wires, make sure the conection to the coil packs is good.... and for the love of god.... check your grounds. and if all else fails.... sell the car to me.

You should cut off the j-tube restriction…….(what is that (sorry)

LOL NO, I would NEVER sale this car.
The exterior is in PERFECT condition and so is the interior. And I got it for 2k from Wisconsin. Read Links for more info……

i have the exact same problem and have tried everything he has said, sometime i can get it to start for a second but die ..im getting codes 14 and 51 every now and then... HELP

EDIT: I fixed it I bet this is your problem, take your coil packs off and clean them very good, all corrision gone. THen clean the plugs that plug into them!

Hope this helps

Hey did you ever figure out your problem? I'm having the same issue. just finished rebuilding a 7M-GTE, brand new everything. finally got all the vac hoses coolant etc routed correctly. but i get turnover all day with no start. i do see/smell fuel in chambers and exhaust. i've checked all plugs, i DO get spark. tried numerous adjustments to CPS. after 3 hours of screwing around i finally got it to we're it'll put put. crank....... about 5 sec. put put. crank.... engine timing perfect. checked already. tried cleaning EVERY connector... especially coils with electrical cleaner. all connector snap in place and have good contact. tried disc/reconnecting cold start injector... no luck. help please



Side Note: engine in car, no tranny mounted, but i connected the reveres and rear speed sensor JUST IN CASE for grounds ect.all ground straps connected,

except i dont' know what the nipple on bottome of wrinkle hose (where stock BOV, MAF and turbo inlet hook up. so i plugged it. i had no other open vac/boost lines. everythign connected. tried gettign ecu to throw codes and i get nothing unless i press throttle IN car all the way down... then i get a TPS code.... also if i floor it. the TEMS( elec. suspension adjustent???) it's at 2 LEDs lit, but when pressed to near/at full throttle it shows a 3rd light. just wanna make sure its' normal. THanks for any help!!!.

wow... sounds like some intense problems you guys have

14 is ignition signal


Diagnosis
No "IGF" signal to ECU "A" times in succession.
A = 6-8 (7M-GE)
A= 3 (7M-GTE)

Trouble Area
Igniter and ignition coil circuit
Igniter and ignition coil
ECU

make sure you coil packs are grounded

is anyone close to you that has a spare ignitor you can try?
