2 Litre, Hpi, 2002 Model Non Starter

[Pipemagics]

Hi guys, newbie to the forum so looking for some advice, i have a C5 2 litre hpi 2002 which will not start, it will fire chug a little and die, has fuel, has spark, but seems to be choked up, take filler cap off and appears to have exhaust gases flowing from the oil filler.

No oil in water or vice versa.

would a faulty egr valve cause this problem?

Welcome to the forum.

 

You probably need to do a diagnostic check, possibly checking the coolant temperature and fuel pressure in case it is not fueling right or one of the fuel pumps or fuel pressure regulator is faulty. You could also have a look to check the air filter is not blocked and there are no air leaks or splits in any hoses and check the throttle body/plate is clean. You could check if the MAP sensor is blocked, the Haynes manual shows it is located under the inlet manifold on the EW10D engine.

 

Excess fumes in the cam cover may indicate a worn engine or blocked breather system but would not come from the egr valve since this directs exhaust fumes in to the inlet manifold.

If the car has been stood up for some time there is also the risk of the hydronic adjusters are air locked. The old nova use to suffer this after a head gasket change we use to wind them over until the oil light went out and go for a cups tea come back and it would fire up a bit lumpy for a few minutes but it would clear as the air came out of the adjusters. I own a c5 hpi petrol not had this issue yet but would be worth checking fuse 2 in the under bonnet fuse box and pin 11 and 12 on the grey plug, these are the power supply to the tank pump and are well known for fuel issues on this model. A replacement bsm fuse box is about £ 175 from the main dealer but there is a fix kit available from them also. It is also if at hand and you have a basic engine reset tool code reader to look at the live data when you try starting it. Fuel pressure should be at 30bar at idle and upto 120bar at 3500rpm the tank pump should between 5bar & 8bar this should show in the live data before you start the engine. I hope this helps you a little as there is very little knowledge on this hpi engine citreon are scare by it and refuse to give part numbers on some parts if you face that issue go in the back door through the nearest Peugeot dealer.
