blacktop wont fire -ASAP HELP please!

[Santa'sBoostinSleigh]

ok well i turned the key in my blacktop conversion last night and no luck

the starter cranks, but the car wont start

coil has power,
ecu has power
ignitor has power on 2 of the wires
injectors have power
fuel pump is making noises

pulled out a sparkplug, attached a lead and earthed - no spark
(all of the leads are brand new)

any ideas?

this damn car needs to go asap or i wont be making it to trackday!!

attach test light to injector plug and see if it is flashing while cranking.
If it is not it means that ECU is not getting crank/cam shaft position sensor signal, or there is no sensor/ECU ground attached to the engine.
If it is flashing, that means ignitor is not grounded, or faulty, or coil is faulty.
Check for codes aswell.

is this using stock ecu?
as others have said check your grounds

[KinLoud]

A classic is that the ignitor isn't earthed.
Also check all the plugs are plugged in. Tricked myself about 2 weeks ago - could start motor, no spark, found one of the 2 ignitor plugs wasn't plugged in!
Any codes from the computer?

havent checked codes (to be honest i dont know how (n00b) - nick didnt wirealot of stuff up, or said it can be worried about later)

standard computer

tried another coil with no luck.

body of the ignitor is earthed (checked with test light/multimeter)

and my ignitor only has one plug?

also, as a double check, should i earth E01, E02, E1, and E2??




W is not connected and i have temp. hard wired the fuel pump (so FC is not connected either)

BATT and B+ definitely have power




and for some odd reason the engine fan always goes when the key is on :S

[sergei]

all the E, E0 should be earthed, the fan is running because you have to short an A/C pressure switch plug on the loom.
There is second part to earth which should bolt on to the head.

[Santa'sBoostinSleigh]

cool thanks, will try after tea!
the head earth is the brown wires right? (thats connected)

That would be because you have removed air conditioning, there is a pressure switch on one of the ac lines, with it not plugged in makes the fan/s go. either plug the switch back in, or bridge the plug.

any idea which plug?


im guessing its bridging the two prong plug?

[Rick]

Iam 98% sure its the one marked in the photo below (which is pluged into the ac lines), I will have to have another look in the day light to confirm. Do you still have the a/c sensors, switches etc.. if so you could try and plug them back into the empty sockets

[Santa'sBoostinSleigh]

its alive!!!!
....kinda

still needs work but she runs
ecu wasnt powered up correctly, its hotwired now
got the fuel working ok
no rev counter
no idiot light

this is the damn rangiest car ive ever owned....

i plugged a socket thingee into the 2prong plug, now the fan doesnt go all the time (havent checked to see if it goes when hot yet)
