Ok. Is this with the key on? or the engine running? We need to know what the fuel pressure is at the time of a cold start. Follow me? So basically what we are looking for is , run the vehicle with the guage on....shut it off, let it sit for a period of time and then look at the guage before starting the vehicle.....what's the pressure? Make sense? Let me know.....sorry for the confusion. I greatly appreciate your patience and will do everything I can to assist you in fixing this problem!
Ok. Quick lesson on how this works. Every time that you click accept....you pay the selected amount (in your case $15). You were only supposed to click accept when you recieved an answer to your question. Right now we are still working on getting the problem solved, so you shouldn't have clicked accept. It shows that you requested a refund, so the Moderators will contact you about clearing this up. Like I said before, I will help you with this until the end, so if you just want to make the ONE payment now thats fine. Or you can be refunded the full amount and you can pay me once we get this problem fixed. If you have any other questions about this, let me know and I will be glad to clear it up for you. Now back to the problem at hand.
The common problem with the situation you are describing is loss in fuel pressure after the vehicle sits. This is why I wanted you to take a fuel pressure reading after the vehicle has set for a while. Do you think that you could take this reading? Let me know.
o really?? is there any possible way you could send me tear down pictures of it... casue when i took it apart the old one did have a vaccum line on it (Online) -- 2 Accepts / 2 Questions (2 Open)
This is what you posted earlier
Ok. And does this engine have Sequential Fuel Injection-Injectors
Central Sequential Port Injection-fuel tubes to popet nozzles?
I think that you have the two confused....I did some more looking into it. This regulator does recieve its vacuum supply from the manifold. So lets forget about this for now. Lets concentrate on cold start fuel pressure. Do you still have access to a fuel pressure guage? If so....lets take a cold start fuel pressure reading (after vehicle has sat). Let me know the results.
There is no vacuum line running to the regulator simply because the regulator is under the intake manifold, surrounded by manifold vacuum. The pressure for this engine MUST be between 60-66 PSI pump running and engine off.
May I ask a few questions?
1) Is the engine (or ses) light on after you pour fuel into TB unit and successfully start engine?
2) How does vehicle run - after you manage to start engine by adding fuel? a) Runs well? b) Runs rough? c) Runs unusual, like I've never experienced before?
Your phone number is XXXXX out in your post. However, we can handle this right here. No worry. I'm very experienced. Please answer my questions. No run around.
Your check engine light is obviously ON. What are the exact code(s) ?
Is your scanner able to read furl trim values?
Sorry for previous typo. I meant 'Fuel Trims'. What is short term; S/T and long term; L/T fuel rim values?
THIS IS A DIFFERENT EXPERT.
I have posted a tip on your other post. I have posted this as a "info request" so as not to incur any additional expense to you. You can access this tip at
Apologies to the other experts involved. Normally I would send an assist post but in this case I felt more direct action was called for.
