View Full Version : Car not starting anymore... what could it be?

So my s13 with redtop sr20 doesn't start anymore... heres the story... This is the 2nd car I had the motor in, 1st car blew the headgasket, had a trusted shop change it. Swapped it into new chassis, ran fine after that except ran VERY rich because it wasnt tuned for 550's so I rarely drove it. The car then sat for a month until I got a enthalpy tuned ecu. The day I put the ECU in it started up and ran fine, but i didnt get to drive it since i was in the middle of a q45 brake upgrade. I got a beater car, and was busy and the car sat for another couple weeks, in that time the battery died from the stupid factory alarm. I ripped all that junk out and jumped the car and now when I try to start it it just cranks forever and doesnt start.

The car has spark, the ignitor chip is fine. All the fuses are fine. Checked the injectors and they pulse. There is fuel in the rail. The spark plugs dont smell like gas at all. Compression is decent 150 across the cylinders. I just cant seem to figure this out and i'm totally out of ideas.

The car has-
hks cams step2
greddy valve springs
apexi headgasket stock thickness
gt2871r .64
#24 topfeed injectors on custom rail
z32 mafs
walbro pump
enthalpy tuned ecu for cams/turbo/z32maf/injectors

and a bunch of other stuff that isnt relavent to my problem

if you guys have ANY ideas please post them i'm willing to try anything!

does your fuel pump turn on? can you hear it turn on?

yup i hear it, and i even did the line in a bottle, turn key on, watch it squirt out procedure

C'mon man, air, fuel, spark, compression?, make sure your ecu is tighetened securely and that your motor is grounded in the right locations, if not that check timing and bov to make sure it's not stuck open. Make sure no one stole your spark plugs also.

figured it out, the alarm had 2 parts to it and i only ripped one out, the other was spliced into main igintion harness and grounded with some sort of switch. removed it all and it starts fine
