I got problems. I've been away on missions for several months, I get home started up the 85' 5speed and went cruising. She ran great. I went out, cleaned her up, bought some new tires, and drove her for three stright nights in a row. Then Sunday evening she just wouldn't turn over. I'm trying to swap out my fuel pump relay with the horn relay to see if that'll get me started again but I can't get the damn things out. Whats the trick? Is there a small button I should know about?
Help me please. I miss driving my car and we haven't much time together.

If the engine won't turn over with the key it's not the fuel pump. The relays can be a bitch to grab. Try to get an edge under it and pry it out.

Well, okay, but should I disconnect the battery first to eliminate chance of damage. Were you talking about a plastic edge?

I just got off another thread for the best Porsche ever and the 928's have it. I had a small 911 back in 84' but I would much rather drive my 928. So somebody help me get her back on the road. The 911's don't get the looks my 928 gets.

Yes, disconnect the battery first. I agree that the relay is not the problem if it doesn't crank. If it does crank but not fire the relay could be the problem. Was your alternator working? It could be that the alternator was not keeping up in the few days you drove it and the battery is dead now.

You need a little piece of metal with a right angle to pry the relays out. something like you use to pry the lid off a paint can.

Thanks for the advise. I guess I didn't use the right language earlier. I turn the key and she sounds like she's gonna fire but won't. I don't hear the little hum from the fuel pump so I'm guessing the relay went bad. I'll try the paint can thing in the morning. I just have to disconnect the battery first. I didn't think this was gonna be all that difficult.

This could be the motto of all 928 DIYers!

As recall you can get a better grip on the one to the right of it. See if you can get it out and then you will be able to get a better grip on the fuel relay.

You might want to check for voltage at the pump. Not too hard. It's under a cover roughly below the right-side back-up light. A couple of bolts and you're in.

The pump should run for a moment when the car is turned on and then go off until the engine is turning. (Spark plugs sparkling, I believe.)

Thanx for the advise guys. I got alittle hot in the garage last night and I wasn't doing to well so I put her down for awhile. I get back at it tonight. The relay just to the right is already missing... I don't have my chart in front of me so I don't remember what it was but thats why I'm so suprised, I get a decent grip, it just ain't coming out. "I didn't think it was going to be all this diffiult". Theres a guy up the street who works for the Bluegrass Motorsport (P-dealership) that I'm hoping I can get to come over to take a look see. Thanx again.

Perhaps give it a shot of some innocous lube ( like WD-40), pull the battery groung strap, and use a 90 deg pick/ bent piece of stiff metal to wedge under the rely base. Some use channel lock pliers on the relay can - this is good to wiggle the little loose, but can also pull the cover off.

I have yet to find a relay that is more stubborn than this, available at most hardware stores.... Get the short end in under the base as Garth says, and "POP"

Adam it is a $12 relay same as your horn relay so disconnect the battery grab it with plyers and pull if you smash it you smash it. Replace with horn relay or wedge the contact points together toothpick and you have a test jumper relay which stays on all the time. Do not have the fuel pump running very long without the engine running.

As suggested above, I too got a better grip by removing relays next to the fuel pump relay.

Also, if money is no object, I believe 928 Specialists sells a special tool that's specifically designed to pull relays. Its a pair of needle nose plyers with squared metal brackets welded to each tip.

Good luck,
