installing a running 90lx motor into 89 Gt, using engine harness from motor connected to harness in car.
Fuel
-40 psi on fuel rail
-with spare injector plugged into harness in bowl of water it open, also power at red wire on injector
- changed filter
-cleaned old fuel out of tank
- spray throttle body cleaner into MAF it will fire

Timing/elect
- double checked firing order, timing
- good spark at plugs
- MAF ohms out oK, power at MAF
- compression is good
- ground between chassis-batt, harness-block,
chassis-batt

one thing is the plugs never look wet,
What am I overlooking? and where to go next
I dont have belt or any exhaust hooked up but why should it matter

do you have the injectors hooked to the right plug?

if it starts when you spray cleaner in the intake then it is def a fuel issue are the injectors pulsing did you try a noid test?

does it hold fuel pressure when you crank it ?

check all vac lines .
