hi all, my '96 wont start!
Worked fine yesterday morning & all afternoon, parked it & went to turn it on about an hour & half later & wont start.
Immobiliser doesnt seem to be the problem, engine turns over quick enought, checked spark ok, checked fuel system fuses ok????
Only thing that has been a bit dodgy ;ately is the fuel guage seems to go down about 1/4 tank rapidly - flase reading then rights itself. Definately at least 1/2 tank of fuel in it.


ANy ideas & also how do I check the fuel pump/where is it?

Not sur but i think the fuel pump is either inside the rear nearside(or offside) wheelarch or, it could be in fuel tank itself..With regards to the non starting it could be the fuel injection relay or auto choke playing up..Have,nt done much with the 3.9 V8 beasts..:cool:

Just trying to help...Thought thats what a forum like this was all about...Obviously in your case, and a few others on here i was wrong eh??.:confused:
 
so, explain how yer helped by saying i aint sure where yer fuel pump is and i aint sure why it wont start
 
the problem with the 3.9 is that its electronically controlled, the good thing is that if you call out the aa/rac they will plug diagnostics in and tell you whats wrong ;)
 
you obviously cant read then, there are a lot of helpful threads mixed in with loads of banter, if you dont get the joke that aint our fault

Added to ignore list!...I,ll talk to the intelligent members on here! Not the ones that creep on when there MUM aint looking...SO SAD!!!:rolleyes:
 
I'll chuck in my two pence worth.................

you say you have a spark but I reckon it's not strong enough, reason I say this is because I've had this problem before, It's caused by the "spider" or immobiliser unit.

Check the voltage to the + side of the coil when cranking, it should be 12volts, if its reading 9 or something like that then put a wire from the battery straight to the + side of the coil and try again, if it starts then the next place to look is the spider which is located on top of the heater box (the center of the dash needs to come out)

Take the immobiliser ecu out and take it to bits, you'll probably find a "dry" joint on the cicuit board, solder it up and try again, 9 out of 10 ecu's can be repaired this way, I've had a few that is a relay fault inside but its normally a bad solder joint, during use, the ecu does get quite hot and this is what cracks the solder joints.

You say you have fuel to the engine so i suspect a fuel sender fault, however, I would throw a couple of gallons in just to make sure, If you want to check the fuel pump, its located in the tank, you can get to it via an access pannel in the boot floor.

good luck!!!!
