I had the same thing happen to me today. loosen the bolt head on top of the spin on filter and hand pump until all of the air bubbles come out.Then I had to crack the nuts that fasten the injector lines to the injectors.Then cranked the engine until the fuel comes out of the injector lines at the injectors.Then tighten the nuts and a way you go.Your engine is fine. Is the bolt on top of the spin on filter to bleed it out.Is the washer under the bolt in good shape?

Austin, when I said to "crack" the hard lines, I want you to break the nuts loose at the injectors......one turn will do it.

Now, this procedure is interesting. I'm not aware that anyone has managed to use the primer pump to force fuel through the injector pump and out the hard lines. I had thought it to be impossible, and, therefore recommended cranking the engine to rotate the pump and cycle fuel and any residual air right out the cracked hard lines.

You are welcome to try his procedure. Just keep mashing that primer pump and see if you get any fuel out of the cracked hard lines. I doubt that you will be successful, however.

If not, then just get in and crank it per my previous post.

Nah.......don't bother with it tonight. Too much chance for error.

Get a fresh start with it tomorrow morning.

DO I crack the nuts on the Ip side or the INjector side?

That uis where the INjectors are. On the block.

Or does it actually matter?

They are not bolts.......they're nuts that secure the hard tubes to the injectors.

Usually, they cannot be that tight. It takes a good pull and they crack loose. You have a good open end wrench?

I don't think the PB will get to the threads.......but......hey.......can't hurt.

A little bit of heat always helps.........but.......be careful to keep the heat on the nut.......not on the hard line.

As long as that's all that cracks...this IS a 21 yr old car ya know.....
I have a couple of nice wrenches, but there is no room to turn a wrench once it is on these nuts. A big plyer gives me better room....

NFW on the pliers. That's not going to happen. All you need to do is crack the nut loose with the wrench. It can be fitted in there to perform this task.

So if a 17mm wrench fits it, is it a 17mm nut?
