i'm lost and need help...
After reading some posts. I change my chts, thinking that could be one of the problems (it looked pretty bad)...I have spark but my car wont start and my plug are still wet with gas.

my car...280zxt with 300 ecu swap
I notice my fuel pressure hits 35 psi when I turn the key. Crank it but wont start, turn it off and The pressure drops to zero. Is it supposed to stay at 35 or drop? maybe my fuel pressure reg is faulty?
The car has sat for a few years...
I believe I dont have leaky injectors... I believe my timing is correct.
I have not lost any coolent... Gonna buy a new dis cap... Maybe my spark isn't strong enough? Any advise thanks

 

so my z32 ecu swap wasn't working out cause of my maf. Change the maf and now the car can idle...but I still have timing issues. I put it to TDC and its right at zero degrees but my distributor is not lining up with number 1
It point to number 4. (the one beside number 1 clockwise)
Are there any detail instruction on how to fix this.
I unbolt the 4 bolt on the oil shaft... turn it and line up and bolt on. That easy? what should I look out for? Thanks

 

You are running a Z32 (90-96 300ZX) ECU on your 280zx????? Or did you mean Z31? What MAF are you using?

 

sorry z31 ecu
z32 maf

 

Are you running NisTune on the Z31 ecu? IIRC, you can't just slap on a Z32 MAF with a stock Z31 ecu.

Where are you getting all this info to put these parts together? Please give as much info as possible so we don't have to play the guessing game.

 

Your AFR is probably out to lunch. What injectors are you running? Turbo or NA ECU?
