so my 93 two wheel drive s10 refuses to start. i drove it home from work at 345 and at 6 i went out to start it and nothing. the starter and fuel pump all work and everything. i browsed on here and read about the spider fuel injectors causing heck... mine was replaced two years ago. i smell raw gas in the oil fill cap. nothing from exhaust. new battery..... please help i go to work at 4am. current time is 632pm

 

best way is to diagnose the fuel system

sounds like you have leaking injectors or bad pressure valve

 

Smelling gas in the crankcase isnt a good sign..
Some people dont know that flooring the pedal and holding it there after starting to crank will minimize fuel delivery and clear a 'flooded' condition.
pumping the pedal will send more gas... yes just like a carb and that's on purpose.

 

if it is injectors then would it be common for them to all the sudden go out?

 

mine did its possible you had a pinhole leak and now it got larger over time

doing a leakdown test would show you if your fuelsystem has a leak

 

is there a way i can test it tonight... or is that a in a shop kinda test

 

you can pickup a gauge at your local auto parts

some auto parts have a loan a tool program


a gauge shouldn't cost no more then 30 40 bucks if you cant get a loan

the link i posted above has all the information you need to run the tests

 

Actually I have come to the conclusion that the fuel regulator on the spider is just a POS and always fails. It could be because of a vacuum leak or the timing being off or something but I have gone through a few in the last few years and that is why I would like to roll my truck out to a corn field and blow it up! If you take the top sensor off the plenum and smell tons of gas in the intake it's the regulator. Yes you can get a fuel pressure testor but that will only tell you that you have pressure to the spider. Save $ and just get a new regulator and expect to replace it in a year or so again. And since your oil smells like fuel then I am positive it's the regulator, change your oil as well.

 

Lindertech used to sell a conversion piece that allowed the use of the newer SCFI FPR on the CPI spider. The SCFI FPR is a much more robust design and very rarely fails, unlike the factory style CPI FPR. Why no one else in the aftermarket has improved the design is baffling...
