84 308 QV 308 starting problem when engine is warm

[hlancer123]

When the engine is cold car starts right up and runs fine.
When engine is warm or hot need to crank engine 3 or 4 times to get it to
start and some times you have to wait for engine to cool down to get it to start. After it starts car runs fine.
Any thoughts on what problem is and what to look at to fix

check the fuel pressure when cold and hot. if control pressure is too low when warm, it's a hard start. check the rest pressure. if it drops off in 5-10 mins, that's a hard start. rest pressure should last about 20-30 mins. pull the injectors out and see if they leak. if they're steel, they will. ferrari, mercedes, volvo, etc. went to brass injectors because the steel 1's rust and leak. if they leak, that's too much fuel and that's a hard start. and if the spark output is low from the ignition, that's a hard start. good luck, chuck.

Check you Warm Up Regulator (WUR) this is very common for hard starting during normal operating temp.

Possibly, it is your "Fuel Accumulator". This item contains a diaphram which may be ripped. To temporarily bypass this, try holding the accelerator down halfway before cranking. Then, crank the engine up while still depressing the accelerator halfway. You don't want to let this problem go too long, because it will start affecting your starter (a clicking sound from the interior right side dash panel).

Thanks to everyone who helped me with this problem. Now have new problem

Have done following
Swapped out from other side

2. Digiplex
3. Coil

Wires from sensor to Digiplex has continuity even when front bank is off
Gas dose not seem to be problem
