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!!!.
