Customer Question

1999 Tahoe 5.7. 160k
I have replaced Starter, fuel pump [few months back], Fuel pressure regulator under the air intake, and just replaced the crankshaft sensor thinking it would eliminate the issue of flooding the cylinders with gas. I pulled the plugs, disconnected coil and turned the motor blowing out all the gas, put the plugs back in to have the same issue. It is hydrolock with gas and can now smell it in the crank case oil recently this a spyder injector issue or anything else?

Hi, My name is ***** ***** for the delay.

I will do my best to assist you

\does it flood like this when it is hot and cold?

Customer: replied 1 year ago.
It was cold when we discover the hydrolock initially and never had it running since. It lock so hard and so much fuel that just letting set would not correct it requires pulling all the plugs and not something I want to continue doing.

sorry i missed you,,i lost the internat..

from the way you explain,if it is getting this much fuel..

i would think you have one of two problems.

1-the fuel metering body[spider] is cracked or

2-the fuel pressure regulator is leaking.

remove the upper intake,then plug up the spider and connect the fuel lines,

turn on the ignition and look at the spider injection system to see where it is leaking
