    when i turned the key on, i could hear the fuel pump, and all of a sudden i couldn't hear it energize.

    when i checked the voltage at the back of the truck where the fuel pump is, it only shows 6.5 volts. why the drop in voltage?

    12 volts. Do you have spark? Is fuel pressure good ? Notorious for fuel presure regulator failing and allowing fuel to pass thru vucum hose into intake manifold; Flooding condition.

I have a 2000 chevy Silverado 4.3L gas that refuses to start during or after it rains. Before I start ripping my engine apart, does anyone know how to resolve this? I'm stumped....

Do a voltage drop test on power and ground circuits for engine , PCM . You have mositure intrusion , high resistance problem !
What is the voltage drop?
This means that approximately 2% of the supplied voltage is lost in the wire itself. Excessive voltage drop may result in unsatisfactory operation of, and damage to, electrical and electronic equipment.
What is Voltage Drop Your problem hasn't anything to do with you needing to rip your engine apart . Electrical problem !

Car won't start 2002 toyata ipsum nothing works apart from lights in side and head light's dash doesn't light up either ?? Any ideas

Start with the basics: Do you have all your fluids at normal levels? Does the engine turn over when you turn the key? Check the voltage on the car battery -- it should be between 12.8 - 14V without load, any lower and your battery may be too flat to start the car. That check engine light means the onboard computer does know something's up. Go get an OBD2 scanner and plug it in, read the code, and work from there.

If your engine is turning over, then the fuel isn't igniting for whatever reason. Check your battery, check your plugs, and check your fuel pump to make sure the engine is getting fuel.

Need to test for voltage drop at the ground and feed sides of the relay and at the pump. At 15 years of age corrosion can cause problems.

I own a 2008 Chevrolet Equinox LT. Several months ago, I started experiencing problems with the vehicle. When turning the key to start, it won't start right away and sounds like it's trying to turn over...

Mass air flow sensor maybe ! Be nice to know what data sensor parameters are . Do you know what these are ? Your vehicle has a number of sensors that supply the engine computer with data ,signals what ever you call it ! Do won't to get to technical on you . Your engine has crank sensor , cam sensors , coolant temp sensors , intake air temp . sensor , manifold pressure sensor , throttle position sensor etc.... They have a voltage coming from the PCM/ECM - engine computer , an they send another voltage back to the computer . With progamming inside the computer it knows from these voltage signals what the temp. of the engine is etc.... With a proper scan tool you can see what the computer inputs are . Even a bad coolant temp sensor could cause the problem your having .

Fuel Pump Relay Switch

Underneath your hood, behind the passenger side headlight, behind the core support, is a bank of 2-8 relays. One of those relays is the relay needed for your fuel pump. There will also be a fuel pump relay fuse located there. The relay designation should be on the cover of the relay compartment.
