Engine Noise

[dante2699yahoo.com]

Well wherre do I begin? I heard a pop and the engine died. Will not turn over. What could it be?

[bignickgt]

Oil pickup line might have busted (I hear it's a common thing on these cars)... I hope that's not the case for you. I wish u the best of luck...

[bignickgt]

Oh sorry u have 97 GT, Im really not sure if the oil pickup line is an issue on those cars. My bad.

[dante2699yahoo.com]

So I'm guessing thats internal?

[amp27]

what kinda pop... like low high. like the kinda pop you get when you stick a paper clip into and home outlet? or the kinda pop you get when you break you leg in 2 spots at the same time. or the kinda pop you get with antilag. or the kinda pop you get with gun fire? or the kinda pop you get when sitting on the beach ball made of plastic.

 

WE NEED DETAILS hahah

Does the starter still turn the engine when you try starting?

[amp27]

he did stay it wont turn over. does the starter click?

 

take all your spark plugs out and try turning the motor over by hand. i am thinking you blew the motor.

pops and then the engine seizing is a bad thing... Are there any holes in the block from a rod sticking through...? I've seen that happen before.

[amp27]

is so. just go get some bondo to patch the hole up.

Ok. It popped when gettin on Hwy. Engine died. I don't think anythin inside the engine is broke. No oil leak. It tries to turn over. But I don't hear anythin from the fuel pump. So I'm wondering if the poppin noise was the fuel pump dyin. But its at a half tank.

[subikid90]

Never heard a fuel pump pop. But test the pressure and see if its gone out.

[bignickgt]

Do these cars have a coil? Maybe the coil plug came loose

[987687]

You didn't say it turned over before... anyway, all engines need 4 things to work. Air, fuel, ignition, and timing (both ignition and belt, make sure your belt isn't broken!)

If you're missing one it won't run. So check you have those 4 things and come back.

If it's your pump that's an easy fix. Pull the back seat out and there's an access panel on the passenger side under the trunk carpet.

How loud was the pop?

[Platinum_Racing]

Was the pop more along the lines of a misfire or backfire, or was it a "Metal on Metal" kinda pop?

 

Does the engine try to start? Is there any signs that the engine may be firing, or is it just cranking over at a steady pace?

 

First, if you have any starting fluid or carb/choke cleaner laying around take out the air filter and spray some straight into the intake tube while a friend tries to start the car. If it starts and runs seemingly fine for a second or two then the engine isn't getting fuel. If it tries to start but can't without heavy hesitation then it could be timing. If it doesn't do anything different its ignition.

 

If you get the feeling that its ignition related, it doesn't automatically mean spark plugs or the coilpack has failed. It could also be the cam position or crank position sensor. Without either of these sensors the computer doesn't know when to fire the coilpack, so it doesn't fire any spark at all.

 

Since you said you can no longer hear the fuel pump running, I bet that if you try the starting fluid you'll find that the engine runs as long as you keep spraying the starting fluid. If you stop spraying the fluid and the engine suddenly dies you've found the proper place to start investigating.

Thanks. I will try that in the morning.

[dante2699yahoo.com]

The pop was like poppin a balloon.

[bignickgt]

im thinking timing belt broke?

[subikid90]

Possible. Pull the passenger side cover off and take a look. Its like 6 8mm bolts.

 

im thinking timing belt broke?

[dante2699yahoo.com]

Ok. I will check. Today.

[subikid90]

any new info?

[dante2699yahoo.com]

I really didn't want to pull the timing belt cover off. When I try to start the engine. The engine rocks. So its not the timing belt I don't think. Right? Or am I wrong to think that. I'm thinkin its the fuel pump. I will let you know. Its rainin today. So I'm not goin to do much until I can get it out. What side is the fuel pump on?

[kaz98gt]

Check behind the timing cover anyway just for kicks. It's really simple to pop the cover; the fuel pump is on the passenger side.

[subikid90]

You can hurt anything by pulling the cover off and you dont need to take anything else off to get to it. You could of also lost a tooth on the belt and be off in timing causing it to not start.
