Rb20det Conversion Nearly Starting But Not.

[tarmac]

Hi guys

Just quickly

S13 Shell

RB20DET

Hard wired fuel pump, connected the three main powers for the ecu etc.. Engine is getting spark, injectors are spraying, but it wont start. Have wired pin 43 into the ecu from the ignition barrel so gets power when starting for cold starts. CAS is plugged in

No Vacuum leaks.

Ecu showing no codes (code 55)

Any ideas.

Is it trying to kick over at all?

Big thing is checking the fuel lines are round the right way

Yep theyre around the right way.

Itll try fire but very weakly, e.g. one fire every second.

Is the ecu light ment to turn off when cranking & if my Crank Angle Sensor was stuffed would the ecu show a code? Cant think of anything else? The only earths on the loom are the two next to the ignitor pack and one earth from the battery to the intake manifold. Have tried putting some jumper leads on the exhast manifold to the chassis too. Alternator is still not hooked up but battery is solid so should still fire?

Any ideas?

where u located? I could come have a look if I'm bored

If you have spark, then the CAS should be working.

Have you got compression? Did you remove the CAS at any time?

try start ya bastard i know its not the solution but it help narrow down issue to fuel or spark related
