    After using the chemical (by taking off the plastic thing on the top on the engine and spraying it into the butterfly thing) I was able to drive it all day yesterday and it ran like a champ. As long as I started it every few hours- each time it started right up- only one turn of the key. I had some one tell me that there is some "spider thing" when it comes to the injection and that one "leg" controls it all and that is what is bad. Sorry that I am unable to actually name the parts and all. What do you think of this potential solution?

Fuel pump replaced, crank sensor replaced, coil, wires and plugs all replaced, now truck acts like it's flooding out and won't continue to run.. problem started with truck shutting itself off while driving. you could let it sit and cool off and it would restart but only for a few minutes..

Check that the Idle air controller is not faulty, disconnect it and start the truck again, if the truck starts (running poorly) then replace the IAC.

    That would make since if you are talking about a Vortec Sequential fuel injection engine. But the symptoms are usually a little different:

    Truck starts fine when cold but hard starting, or won't start at all when at operating temp. Hard starting was caused by a leaking fuel pressure reg. On 98-01 Sequential fuel injection Vortec engines the spider assembly and FPR are located under the upper intake manifold. once the FPR starts leaking, the fuel collects in the intake manifold and sits there flooding the engine. If the truck sits long enough the fuel will evaporate and the engine will fire. The fix is to purchase the upgraded Spider assembly for SFI vortecs, this upgrade does away with the poppet style injectors and replaces them with real injectors and is complete including the FPR and is a direct bolt-in.

You need the 3 essentials for proper engine operation.Fuel,spark,and compression.You said the fuel pump is working but the question remains;is fuel reaching the fuel rail.Try starting the car and then take one spark plug out and check it for fuel odor.

My 94 fors Taurus cuts out while driving and sometimes will not start. It cranks but won't start. We changed the fuel pump, spark plugs and distributor cap, but it is still cutting out while driving...

are there any codes? have you checked the pressure in the fuel line. you may have a bad fuel pressure regulator. or a bad crank position sensor. spray starter in the throttle body and see if it starts

Why won't my 1997 Saturn SL start?

you have spark at the plugs ..thats something

spray stay you mug
into the throttle body see if the motor will cough

tank needs draining and have fresh fuel
fuel pump has a filter and fuel relay

crack the fuel line connection to the rail to see if there is fuel reaching the rail and correct pressure

if sitting 6 years.. not being run regularly
do a compression test
lifters may be stuck
rings may have lost tension

2002 saturn sl won't start, turn over but won't start

If the engine fires up for a second or two with starting fluid then the fuel pump is weak.I would check the fuel pressure and if its not within the specs then replace the pump and filter.

I had my spark plugs changed today and now my car won't start it will turn over but won't start

fuel problem or spark problem neither is associated with a change in sparkplug unless you had a sever misfire that you let go for a long time to cause thhe igition module to fail.and this include the crank sensor that is underneath the ignition module. cycle the key you should hear a humm at the fuel tank and that is the fuel pump working if you hear the fuel pump then more than likely you will need to correct for spark ignition module and crank sensor

Hello. My 1997 Chevy Tahoe refuses to start. The problems began with a bad fuel pump. I changed. It worked. The fuel pump died again. I changed it again and it has been working. I parked it for two weeks....

Now you have a good battery & a starter that turns over the motor

Have you cycled the key on & off with a fuel pressure gauge on the
fuel rail?

Do you have a fuel filter that isn't over 3 or 4 years old?

Have you checked for spark while cranking ? Use an old plug on the wires,
if you have ignition wires,don't ground the wire without resistance

If you removed the ducting & MAF Sensor it won't start

Tell us what you checked & exactly how that was done.

Won't start sometime

you need to determine if its a no spark or no fuel problem.check to see if you have spark at the plug.if so then you will need to see if its getting fuel.check this when it won`t start as when its working its check for fuel you can spray intake cleaner into the intake when it won`t start,if it does then stalls when it has burnt what you sprayed then its a fuel problem.the pressure will have to be checked with a gage to get a proper reading.the pressure should be about 35 lbs.pumps are a common problem with this year.if no spark then you will have to find what component is causing the no spark.

Changed the distrbuter cap and the rotor because the truck would not start what else can it be? and the wires and spark plugs

fuel you hear a sound from the gas tank when you turn on the key if you dont its either the pump, pump relay or fuse is bad.
also could be a totally clogged fuel filter but i doubt that. unless you've never changed it since you've owned it.
also check battery voltage, if battery more than three years old then it is suspect...get someone to give you a jump.
