Crank postion sensor disturbed?
Does it turn over and not start or just do nothing?
Remove a plug and check for spark.

The CPS is close to where you were working, I would bet you have disturbed it or the wiring
No cps no spark. But first you need to establish if there is spark.

No spark then check the cps, and that power is getting to the coil.
If you has spark then begin to investigate fuel pump and relay

No spark from the plugs what sort of readings should be getting from the coil??

using a voltmeter from coil pin 15 or +ve to a metallic body part you should have battery voltage (about 13V) with ignition on.

on another note there was once a alarm and immobiliser fitted to the car that does not work anymore would the immobiliser stop the spark?? i alway thought they get wired to the ignition or the starter just thinking of ever possable as the battery has been disconnected for a few months now??

That's why Lee's asking you to check for voltage at the coil + terminal.gnrsoul wrote:on another note there was once a alarm and immobiliser fitted to the car that does not work anymore would the immobiliser stop the spark?? i alway thought they get wired to the ignition or the starter just thinking of ever possable as the battery has been disconnected for a few months now??

Probably this then! disconnecting the battery may have brought it back to life. there are many ways to immobilise the car, interrupting the wire in between the ignition key and the coil is one way although not the most elegant, again test for voltage at the coil with the ignition on, no voltage means the wire from battery to ignition and then to coil is intterrrupted, either by the immobiliser or a break. you could also try to temporarily supply the coil pin 15 with a voltage using a temp lead and see if you get spark.gnrsoul wrote:on another note there was once a alarm and immobiliser fitted to the car that does not work anymore would the immobiliser stop the spark?? i alway thought they get wired to the ignition or the starter just thinking of ever possable as the battery has been disconnected for a few months now??
