Re: 1997 Pontiac Bonn SE Replacing Fuel pump. [phillyfrank]

Written by: ezlead on Mar 03, 2009 03:18 PM

Before going to a large expense on fuel pumps and the like,have the GD burgler alarm system checked. It is the most worthless system that GM ever put on a car. My 97 bonneville does the same thing and it is in the key and ignition switch. When it is warm the switch does not recognize the key and it disables the fuel system. It just cranks and cranks. It even does it sometimes ... Read More...

Is the fuel gauge sender also called a float assembly? Is it the sensor that shows you how much gas you have? If so, I had a new one installed 3 years ago. When I turn my ignition, before I start the car, I can hear a humm from the rear, is that the fuel pump? Can anything else be causing low fuel pressure? Is it difficult to replace the pump in the 97 Pontiac Bonneville SE? ... Read More...

1997 Pontiac Bonn SE Fuel pump or Filter HELP!

Written by: phillyfrank on Feb 24, 2009 07:36 AM

My car doesn't start after it's been running awhile, but it starts great when it's cold. I know when the engine is going to run ok when it goes up to 3 or 4 rpms and it idles fine for awhile. When I go to start it, after it's been running it wants to stall, but if I tap the gas pedal (lightly) it will surge and not stall. Sometimes it seems like no gas is going to the engine. I ...

Re: 1997 Pontiac Bonneville SE Antifreeze Disappears. No turn signals [phillyfrank]

Phillifrank: The bolts around the UIM develope seeps which wick up oil and in some cases coolant which pools in the low spots such as around the bolt in the middle of the picture. The UIM is dry in that area so it's not going to seep them. The coolant goes through the UIM at the throttle body seals between it and the throttle body and about an inch to the left of that where ... Read More...

The date arrow points to 00 on top of the manifold. Below is a photo of the leak, at the bottom of the manifold, under the nut. I also thing there's another leak. In the 2nd pic there's something on the hoses at the bottom of the engine which looks like dex-cool. I'm bringing it to get inspected any day. I unhooked the battery to see if I could get the engine light off, but ... Read More...

I dried the liquid and I'm waiting to see if it reappears. The manifold doesn't have a date on it. I'll be taking my car to get fixed and inspected, and I hope it doesn't cost much. I'll let you know what happens. Thank You for all of your help. Read More...

1997 Pontiac Bonn SE Engine light on after long drives

Written by: phillyfrank on Jan 17, 2008 00:54 PM

I have a 1997 Pontiac Bonneville SE with 115,000 miles and a 3800 engine. After long drives my check engine light comes on, it usually goes off after a few days. This week I drove over 150 miles straight and the light is on. It hasn't gone off in 3 days. Why does this happen? I was told I can't get my car inspected if the light is on. I have to get it inspected by Jan 31st. I ... Read More...

Dry up the current liquid around the manifold and heads by soaking up with paper towels. See how soon it reappears. What was the date on one of the circles for the upper intake? If it was original to the car, it may have had a partial fix applied. I believe during 1999 is when GM changed the size of the metal EGR pipe. DexCool develops a gooop if regular antifreeze (old ...

I bought the car in 05 with 95,798.miles on it. As you suggested, I took the beauty cover off and looked at the manifold, which has (2 half dollar circles and 2 small) I noticed some thick liquid at the bottom of the upper manifold, which looks and smells like the dex cool. My radiator and reserve have thick brown goop, which I had flushed 3 years ago, but it's returned ... Read More...
