[bowtiebuba350]

I 1g will start run and drive but then the next time you shut it off it wont start again until you scre with changeing ecus jumping the car ect... the specs on everything are as follows

good comprestion
good fuel pressure
fuel pump works
no power to injectors
olny one terminal on coil pack plug is hot? is it supose to be?
2 diffrent ecus both work at times sometimes dont booth auto ecus (main suspect)
new mpi relay
turns over fine just has no spark or fuel in the cyl i think.

any info is great thanks

If it doesn't start while still warm/hot (eg. 3-20 min after turning off) it sounds like vapor lock. See here: http://www.dsmtuners.com/forums/showthread.php?t=217349#post1821514
Other possible hot start fixes: http://www.dsm.org/how-tos/JFM/HotStart.html.
How do you know there's no power to injectors? Do you have a noid light on them? The pulse on them is too narrow to measure with a voltmeter.
By coil plug hot you mean +12V? One side has +12V, the other side of each coil is 0V most of the time (while it's charging/charged) - goes non-zero only when firing but too narrow to measure with voltmeter.

ok if i turn the key over and try to start it it turns over but dosent fire, here is some info on the car

-has fuel pressure about 40 psi
-injectors have power
-coil pack has power but olny 2 plugs fire?
-cam position has power
-maft has power
-tps has power
-pulled some plugs but dosent look like they have fuel on them even though i have fuel press and power to them + i have an injector pulse?

new mfi relay also and checks fuses and relays

timing must be off then, or bad coil if only half of it is working

As weird as it sounds my friend's laser I was working on was doing the same thing. I tried everything from a new coil to new plugs. All we done was put a new battery on it and BAM it fired right up. The problem was it wasn't getting enough voltage. We even had a battery charger hooked to an extra battery that was jumped to the battery on the car previous before the new battery and it still didn't fire up.

The only thing it was doing different than your car was it was cranking over very slow and sluggish. Does your car start over normal and not sluggish?
