Wifey's Burb Won't Start

[Texas Jim]

Gary... if you are not getting it locally... be sure to look at ROCKAUTO.COM for prices...
FPR will make it hard to start when the engine is warm.
It will cause a longer cranking time when the engine is cold but usually don't interfere with it starting and running.

The ECM sends signals to the Spider...The spider send the fuel to the injectors...
If the electronics in the Spider are toast... it will (obviously) keep it from running... but spider failures are rare...

The main thing that bothers me is there were no codes.I would think with a spider failure it should set a code..

Does your truck have a FUEL RAIL where you can lift it up to see the injectors???
If it does... lift it and turn the engine over and look at the spray pattern of the injectors.

I am still leaning towards the crank sensors ...lot of times they WILL NOT set codes...

No fuel rail,I believe 454s had them.A new crank sensor isn't out of the question yet,I thought I'd spend the diagnosis fee at our dealership before replacing parts to see what they had to say.

The 94-95 fuel injection spiders were notorious for going bad. Supposedly they were improved by 96. My mom had a Astro van and the spider went bad. It was leaking and filled the intake with gasoline which seeped into the oil and then one day, BOOM!!! The engine literally blew up. There was a hole in the block the size of a baseball.
Check the oil dipstick and smell the oil. If you smell even a hint of gas on it, I would replace the spider.

I also just had a coworker who had this problem on a 01 S-10. He said the mechanic told him the lines on the spider turned to jello from the ethanol that is being put in our fuel now.

I'll be sure to check that when I get it home Can't afford a new engine

If you DO smell gas in the oil, then I would change the oil as well.

Is there a way that the spider can be tested if you take it out of the truck? Maybe it needs to be cleaned.

Could be a dirty plug or connection.

You say it won't start at all and the fuel pressure is good?

I would look strongly at the cam and crank pos sensors.
I know you know this but start simple and work your way up.

Good luck.

Here is a thread on a Vortec 4.3 http://www.automotivehelper.com/topic559014.htm

Gary ... here is a service bulletin for replacing the spider and injector tubes

The replacement part of it starts about 2/3 the way down the page...
