check your coil packs are all pushed over the plugs correctly.

Try wiggling the crank sensor (and cam sensor while you're at it). Then try cranking over...

could you tell me the location of these to sensors if i disconect the battery how long before ecu will reset itself

joz8968

iTrader: (13)

Disconnect for about 1/2 hour should do it (enough time for the capacitor to run down and forget sensor I/O values).

The crank sensor is in-line with the crank pulley and on top of the block, just below the alternator. Cam sensor is on block near to the oll-filler pipe (looks like crank sensor too).

defo getting a good spark just checked now i have to think about fuel

batmanwrx

iTrader: (1)

should i be hearing the fuel pump buzzing if so where are they located also where is the fuel pump fuses

Fuzz

and here we have the answer I bet, the new plugs have fouled up...


Take them out, give them a clean, regap them to 0.7mm if you didn't do that already, bung them back in and tell me it started fine...

THEN GO FOR A DRIVE, not let it tick over and switch off.
Surprising how many times I've seen new plugs do this...

fuzz im thinking it might be fuel as i cant here the fuel pump the plugs were gapped to 0.7 i think we have our wires crossed i done the plugs yesterday then took it out for a good drive last night i didnt just do the plugs then turn it of i ment i let it run down when i got back in from my drive last night then tryed to start it today then nothing just turned over and thats about it

Fuzz

Oh ok...

99.9% of the time when something is wrong with the car immediately after someone has worked on it, it turns out to be something they did / didn't do. Just hate to see you go down a load of roads not related to what you did first.

batmanwrx

right got the back seats out and looking at listening to the fuel pump but nothing i tryed to pull the middle pipe off to see if i was getting fuel but cant get it off and stabbed myself with a screw driver iv got a fluke if testen the conection what should i be looking to get

AzzDSM

Hey up mate. Have you checked the fuse and fuel pump relay?

Found a wiring diagram i had with mine so hope this helps

the relay should have 4 wires coming from it which are:
Black/Blue: (To fuse: FB-9, No.13)
Grey:
Black: (Ground)
Red/Black: (To Fuel pump control module)

The Red/Black wire goes to the fuel pump control module via a conector.

There should be 5 wires conected to the fuel pump control module which are:

black: (To fuel pump)
White: (To fuel pump)
Red/Black: (From relay)
Blue/Green: (Bulk head??)
Black: (Ground)

The Black and white wires go to the fuel pump via a conector.

Somebody correct me if this is wrong. cheers
