very seldom is the reg the source of a low pressure concern
you can easily tell by installing fuel line shut off on the return
line ,if you still have insufficient fuel pressure replace the pump (warning, on properly working system,fuel pressure can go very high do not exceed 50 psi when using fuel line shutoff valve)

It's possible,but most likely you have a bad fuel pump.
That engine needs at least 30 psi of fuel pressure.

You of course have a significant problem right here. Being that your automobile sat idle for see you later, changing the gasoline pump become a great theory besides. With a automobile like this you in lots of cases choose to repair the fee effective issues first. On that style you ought to have a button, on your truck that shuts off the gasoline. Its in the trunk on the left edge....Ford positioned that throughout there for collision applications...So the automobile do no longer blow in a collision. Now, you in addition to mght have your regulator and your pump...at the same time, below your returned seat. So in case you alter one you ought to replace the different besides. i ought to b e incorrect yet i think they are the two at the same time. Pull the returned seat out and take off the ten bolt screws. If its no longer below the returned seat its in the trunk itself. So verify the trunk first....Then only replace the whole unit...Its between 15 and 20 money. Being you have not got the rigidity your think to have, the only different element is probably a clogged line. which you will discover the thank you to blow that out with air. yet be careful you do no longer injury aspects doing that. wish this facilitates. I had a Sable that's certainly a similar automobile and had a similar complication with it...comparable as you. So I warm under pressure that swap and took it out. Then I wrapped them at the same time and taped them.

It could cause this problem,but you can ck it by blocking off the return fuel line to see if the pressure changes.
