The thing is with my cos when im driving it it just cuts out then the rev counter flies to 7000rpm then down. When i go to start it back up it sometimes back fires and smokes like mad but will not tick over the only way i can get it to run again is to unplug the ecu and connnect it again any thoughts of what this could be cheers in advance bri

 

phase sensor and crank sensors are at fault

 

checked phase sensor looked ok to me wires were still intact no burnt signs crank shaft sensor what could be up with that are they easy to replace

 

i'd replace both as a matter of course, just because they look ok, doesn't mean they are

crank sensor is located to the bottom of the crank pully, make sure it is gapped properly, 0.3 to 0.7mm from the crank lug to the sensor nose.

 

cheers m8 will give it a go

 

while you are about it, disconnect the 3 connectors on the bulkhead behind the engine, and check that the contacts are clean, pay special attention to the one nearest the battery with larger wires in it, disconnect and plug it back together a few times to clean the contacts.

 

but for fuck sake, do NOT spray any shit like WD40 on them, it will dry up the lithium grease that helps the electrical connections

 

will give that a try cheers but will not use wd4o

 

good advice from Gracey

WD40 has NO place in electrical components!!!

 

Had the same prob with mine greased up the 3 concetors ran prefect after no more miss fire


and you can by the elec contact grease from ford
Finis 1122540 around a Ł10 for a big tube

 

If it is the connectors causing grief - as a 4x4 owner you will get used to cleaning the connectors as regular maintenance thing

 

Another one would be to check the ign mod on the inner wing passenger side.. Clean up the connections..

I had this problem for 5 months and it ended up being that the earth to the engine was shite..

Brought a earth lead (Like one u get in a amp kit) and earthed the engine directly to the battery. Clean up a connection either end... The leads are usually around a fiver... After i brought/replaced every sensor the cheapest fix of the all sorted the problem..

 

bri still reckon you should try map sensor as its same prob mine had and map sensor cured it
