Throttle is shine clean maf is too both are operating normal ...I'll do cap rotor and plugs and wires on Friday or Saturday

 

How do you know the MAF is working normal? Were you able to get it tested?

 

No not tested but I unplugged it while running and it shut down so I just figured its working ...but I took off distrubuter cap worn pretty bad so I cleabd contact points a Lil and now it won't start so I'm pretty sure that's the problem ... Well I hope

 

Didn't check that out yet bit I took off distributer cap and it was warn and all contact points were white and chalky so I tried to clean them up a bit and the rotor too put it back together and started it to make sure it all wires were in place ran fine 2 hrs later wouldn't start .....so I has to be cap and rotor but while I'm at it I'll do plugs too and let everyone know

 

Is this the same blazer from your other post "hesitates if I give it too much gas"? If it is, your hesitation and the miss you feel are probably the same problem. A/C delco are the only cap and rotor that perform reliably on these motors.

 

Yep same blazer and I will get ac delco you are the third person to reccamend it ,thanks

 

The white chalky substance on the cap terminals is supposed to be there. The terminals in the cap are aluminum and they corrode. When the cap is installed, silicone dielectric grease is applied to the terminals to reduce/eliminate corrosion. When spark jumps the gap, the grease crystallizes. Without the grease, the cap terminals will corrode rapidly and shorten the life of the cap substantially.


Low fuel pressure and or volume will cause a misfire, an not necessarily set a DTC in memory. This thread explains: https://blazerforum.com/forum/2nd-ge...eakdown-88305/ After completing both tests, post all 4 readings.

 

K if u read my previous posts u will know I narrowed it down cap rotor plugs wires well I did the cap and rotor went to start it wouldn't start sooofor ****s and gigs I had someone turn key while I sprayed break fluid in the throttle started and stayed and stayed started until I stopped spraying but here is the kicker I just did fuel pump and filter 4-5weeks ago ...I can still here the pump kick on .... I'm stumped

 

Help please: m going crazy

 

I ran out of gas lol I feel stupid the first time I ever ran out of gas in my life haha
