P38 won't start help Hertfordshire

vippymini · Jul 4, 2020

Good afternoon
Hoping someone can help we purchased a 1999 p38 back in march that's spent more time parked than driven due to various issues but till now.most have been fixable

We now hit a problem it refuses to start
So few weeks back drove it around for a hour in the morning no problem what so ever , went back out in the evening it refused to start it cranks over but no fire

Had a friend over with a diagnostic tool and hawk eye and can't really find a main answer . The hawk eye could not connect to the bcu and kept asking to reset test

I'm scratching head at what else to look at and do any suggestions or anyone local got a Nanocom for a p38 who could help

, as the old saying goes

There's your problem, it wants to be on air.

I take it you have no message on the dash.
Perhaps you need to check your OBD socket is clean then you may get comms to Hawkeye.
Do you have sparks, and fuel first things to check.

Worth checking fuse 33 it's 5 amp,provides power to the obd socket, while your at it.

vippymini · Jul 4, 2020

Thank you so far we currently are running out of ideas , replaced , cleaned etc etc

Fuel yes ,but no sparks

It's had several people look at it so far and we all scratching heads

I would go for the CPS relatively cheap but a pain to reach

marjon · Jul 4, 2020

Aslong as it’s in sync and you have power to coils I would go with ^^^ too.

I would look at loss of sync.

Henry May be close for damsels in distress but coils may put him off

Another thing to check if Hawkeye will not connect is the presence of the self leveling relay under the driver's seat. Will not connect if that is missing.

What "Loss of Synch"? If the car is opening & closing on the fob buttons then the key is in Synch.
If synch is missing as a reason to start I thought it asked you to push a fob-button to prove you had a valid key etc. so it would arm to turnover and fire?
If its turning over, then it has passed all these checks isn't it a lack of CPS signal?

Thing is we don’t know the answers to what you assumed as basic P38 checks, peeps on here know.
A petrol will crank and pump fuel when out of sync, But no fire

.

It does ask to push fob buttons but we still don’t know if the OP has a message on dash

but yes as I believe the cps is the only “single point failure” on the petrol. As far as sensors go.

Battery?

My MY2000 Thor won't. If it loses Synch it just says "Press A key" no cranking till it knows you don't have a big meaty screwdriver in the ignition switch. ;-)

Keyfob or engine ECU sync? We're assuming it is Thor with it being a 99. Were there any GEMS registered early 99?
