Starting issue
Hi guys,
Sice i got my car back after the engine was replaced, at times she seems to take a while turning over before she comes to life. It does not matter if it is hot or cold, weather she has been run for 2 sec or 5 hours. It just seems to take time to fire up. I have replaced the coil, distributor cap, leads, spark plugs and she has had a full service. When she is running, she runs like she is still just out the show room. No low or high revs, no hessitation, no nothing. All it is is the time it can take to start at times. Sometimes 2 turns of the key. Does anybody have any ideas.

I have just has a thought while i have been brousing through the forum. I know the car started fine on the previous engine so that is why i am thinking that the problem is from the new engine its self. As i said before i have replaced the electrical side of things, apart from the cam sensor or possition sensor as i think it might be called. It is still the original sensor that is on the engine, and i kept the one that i had on my last engine, so i might give it a go and swap them about and see if that makes any difference.
What do you guys think?

Does anybody have any other ideas as to what it could be apart from the position sensor. I will change that later on today.

I have just replaced the position sensor and been out for a good run. Unfortunatley it is just the same, and has the intermittant long cranking time. Does anybody else have any idea at all.

stuart, have you checked the timing belt has been fitted correctly, if your exhaust cam is a little out this could lead to the fuel being dumped before the spark requiring a long crank to build up enough gas to ignite....
you may also want to consider whether or not the pressure regulator is operating correctly and is not stuck open allowing fuel to return to the tank.. other options could be incorrect plugs or low compression cheers jod

Hi Jod. Thanks alot for your reply. I have been pulling my hair out. I have also just finished replacing the fuel filter there, as it was something else that was needing done. I know that the correct plugs are in it. I am pritty sure that the timing belt has been done correctly although i will check upon this. Where do i find this pressure regulator that you speak of. As yet, this is not a part that i have worked on, so this will be a first. If you could tell me exactly where it is and how to check it i would greatly appreciate it.

the only way to check its operation is to have it professionally checked, because i am not sure as i sit here of the vaccum specifications.... alternativly twin turbo is breaking his t5 so may have a spare aftermarket adjustable regulators (fse) are available too cheers jod

I have a spare regulator sitting in my garage which i kept with the injectors and rail. I will swap over the regulator tomorrow and see if that makes any difference.
If anybody else has any ideas please let me know.

I have just replaced the fuel regulator. I thought that it had fixed the problem, but i think the problem has came back. I have read alot about this fuel pump relay. Could it be that, although i am sure that i hear the pump each time i turn the ignition on though. Any other ideas.
