86.5 7MGE wont start , no spark
ok .. heres the senario ... i bought the car with a 7mge jdm engine just installed .. the guy i got it from couldnt get it to start ... i got it home .. checked the timing checked the wiring .. disabled the alarm .. it acted like it wanted to start ( had a few backfires in the process) still had spark .. drained gas tank , added fresh gas , checked every thing again (although there is NO hole in the camshaft or camshaft journal for the timing.... at all) re checked the distributor .... everything was copacetic ... then it fired less and less .. so we checked the coil , ignitor and distributor again .. set the vehicle security system back how it was supposed to be and now ... even after changing all of the ignition system (even though it checks out) ... again .. no spark .. non from the coil .. (yes the brown wire reads 12 + volts when the ignition is on ) primary and secondary readings are both within tolerance .... the injectors are correct (yellow top) ... have tried three different MAF units and two different computers (yes there is power at the computer ) compression is 85 pounds per cylinder (pretty much all of them are really close to the same .. within one pound .. better than any honda i have ever worked on ) ...checked grounds ... all good .. the only thing that i see that doesnt seem quite right is a little blue two prong wiring connector under the intake manifold that has a red with a black stripe and a black with a red stripe running into it ... please help .. this is my first supra .. i need to be enlightened .. thanx.
