well here is the problem, worked on a Malibu with the 3100 engine that belongs to a female friend.
someone put sugar in her gas tank. she had someone clean the tank, and replaced the fuel filter. worked for a short time then died and would not refire.
had it towed to my place and replaced the injectors and fuel pressure regulator.
it was running fine for about a day and a half. then it started to quit running while she drove it. now, when it just sat and idled, it would run. but when she started to drive, it would go a ways then die again.
I even disconnect battery, and reconnected it and it went further than before. then last night the distance started getting shorter.
she also said just before it dies, the temp guage would show very hot, but it was not boiling over. there is coolant in the system.

now also when I got the injectors in, it would not start. I charged battery because it was low on charge. let it sit overnight, and went out and when I turned key on the fuel pump made a stranger than normal noise. I turned switch on and off about 4 times then the pump sounded normal and it started. ran great for 1.5 days and started to die when driving.

also someone had jury rigged the passlock system with a couple of switches. not sure if that would be causing the kill of running.
this is a strange problem, and any good advice would help. she does not have a lot of money.
thanks
