V6 cranks but doesn't start

Post by burt » Tue Sep 12, 2017 6:55 pm

Hi,
Hope someone can help. My V6 won't start. It has a spark and I can smell fuel. It does try to start but doesn't? Any help would be much appreciated.

Hi

Welcome aboard, and sorry to hear you have a problem.

Does it have an imobilser?

Even an empty tank will smell of petrol, is there definitely fuel in it, and has it been sat for any length of time? Fuel does go 'off' with time.

I'm sure others will have some thoughts, but meantime I'd try the Search facility on here and trawl through some old posts. Just put 'and' between key words, eg Bongo and V6 and not and starting.

Good luck. [-o<

Has this happened suddenly? Had it always started perfectly before? Any link to the appearance of wetter and/or cooler weather? Ignition related stuff would be my prime suspect. Coil, HT leads, maybe even crankshaft sensor. Worth searching old threads for other v6 starting problem discussions. And hopefully someone more technically savvy than me will be along with thoughts. Good luck and keep us posted.

Check the timing/cam belt and valve gear,also the ignition timing and distributor drive gear.

Good Luck.

Anything else of note like an LPG conversion? Did the problem happen suddenly? Had you been thru a big puddle? The crank position sensor is low down and quite exposed. Have you tried some Easy Start squirted direct into air filter box? If it runs a bit longer on gas, then you're probably looking a fuel supply problem, possibly with the in-tank pump. Have you checked you're getting sparks at all 6 plugs, and is there any possibility that the HT leads have been fitted in the wrong order, perhaps as the result of doing some other work on the engine?

Hi, I have replaced the ht leads, dizzy cap, rotor arm and plugs. It now starts but only running on 4 cylinders. I have now found that the injectors on the 2 are not working. Think they may be blocked. Have got a set on order. Fingers crossed. [-o<
