Re: '94 LT1 Never-ending problem
Also, the LT1 is not a 4.3, it is a 5.7.....
Temp sensor in the water pump? As stated, start your own thread with it's own unique symptoms..... |

Re: '94 LT1 Never-ending problem
Thanks keyboard king II, peeps in motor cycle forms are nicer, my v8 says on the radiator housing that its a 4.3l v8 and as I look at the motor I can see the water pump and the opti spark distributor behind it. So instead of telling me I don't know what I have do the nice thing and tell me what you think it is?

Re: '94 LT1 Never-ending problem
LT1 is 350/5.7. The engine you have is an L99. Sometimes called a 'baby LT1'.
It would be more helpful if you lost the attitude - nobody wants to waste time with someone who is a complete jerk.

Re: '94 LT1 Never-ending problem
Thanks j cat, I'm doing the work so I can only blame myself and I have 95, I may found problem the fuel pressure is jumping all over and finally dropped to 10 psi yesterday and she won't run but was giving the intermittent fault before got to the non start state. May be that hose in the tank but I have a new pump already just in case. No serv engine light at all.

fuel pressure is 41-47PSI key on engine off. engine on pressure drops down to 38PSI area. this is because at idle , high vacuum to the fuel regulator drops the fuel rail pressures. what may be bad is the in tank wiring as well. the fuel tank must be at all times above the 1/3 mark. the in tank fuel level sender reports more fuel on dash than you really have . the pump motor and wiring connectors over heat then the pump gets a lower high resistance connection. when you open the tank and see burn't looking wires at the connectors this is very common at this age point. check the wiring in the trunk. this is driver side, also the ground in trunk driver side as these wires supply power to tail lights and pump. open connectors look for bad pins. the heavy wire goes to the pump. then you have the under rear license plate pump connector to measure for voltage there. key on engine off voltage will be about 11 volts not 12 volts because the wire has some resistance that drops it down 1 volt or so to 11volts.. check out this video https://www.youtube.com/watch?v=MO6ofN8ZJBc |
