I have bought a 3.5 V8 (1992 on a 'K') to start it I need to have the accelerator flat to the floor, otherwise it just turns and does not fire. It will than start and run without any problems. Any ideas?Regards,Nige
Get any smoke out the back when it does start? Just to make sure she is actually getting fuel, if it starts fine when you have your foot down but then runs fine when you take it off (it ticks over fine etc, dosent drop down to very low revs) then maybe you need to check the condiation of your plugs.
Its the EFI and no smoke out of the back on starting, runs beautifully once going; just a pain if you forget to put the foot down. Does not stall even after a good run, revs solid at about 750 on tickover.Nige
The first that would come into mind in this case:
Coolant temperature sender faulty (or poor connection, infinite resistance). ECU feeds too much fuel when the engine is hot - thus, hard to start.
Easy to check and cheap to replace. There's a connector near the thermostat housing. Unplug it and measure the resistance between the sensor pins with a multimeter when the engine is cold, warm and hot. Resistance should be around 1.5(?) kOhms when cold and start to come down when the engine warms up. When hot around 200(?) Ohms or so.
(I do not remember resistances and temperatures accurately by heart and have no energy to check them at the moment - hence the question marks.)
However, the resistance should come down in an even manner when engine warms up. No gaps or jumps allowed. If it keeps up to kOhms the sender is definitely gone. Or if the resistance is low when the engine is cold the sender is also gone.
