Hello

as you've already replaced the sensor I'd suggest the next step is check over the state of the wiring to the crank and cam sensors - ideally you would disconnect the ECU from its socket and the sensors too and then do a continuity test between the two to check for wiring damage

I'd also check the state of the engine earth connections both the large ground wire onto the block and chassis rail / battery ground

and there should also be a smaller earth connection for the engine bay wiring loom thats secured to the engine with a ring terminal and small bolt

Hi
do you still need help?
Bear in mind that the site takes a deposit from you at the beginning and this is held by the site until you rate my answer at which point the cash is split between the site and the expert. I am only paid for my work on this question if you rate my answer, using the star system at the top of the screen. Please do not forget! If you're not pleased, also let me know because rating bad does not result in a refund, there are better options. Rating now will not close this post nor prevent further replies
Thanks Matt
