My ignition switch broke a while back, so I have it hotwired. I poured some dirty water into the gas tank a week ago, it started running poorly so I put heat in it then it just quit working. It took me pouring gas into throttle body to start it, it ran for two days then does it again runs idle rough then shuts off. I cannot accelerate now at all it stalls out. is it the fuel pump?

Hi,

If you poured dirty water in the tank, it may have damaged the pump, but I would think it is more likely that you have plugged injectors. How dirty was the water and what was in it?

Next, it wouldn't be a bad idea to check fuel pressure. You will need a fuel pressure gauge. If you don't have one, most parts stores will lend one to you.

Here is a link that explains how it's done:

Also, I attached the manufacturer's fuel pressure specifications below, so you have it.

Let me know what you find. Also, let me know if you scanned the computer for codes.

Take care,

joe
