Check for vacuum leaks. You can do this with a can of carb spray but please be careful as it is flammable! if the ignition wires are leaking and you hit them with carb spray you will start the engine on fire!

The safer alternative is to have the engine "smoked" for vacuum leaks. This is done with a smoker. Any place that is leaking you will see smoke.

A trained ear will also be able to hear a leak.

If no leaks are found try unplugging the MAF sensor. Is is in the air tube next to the air filter box. If performance improves try cleaning it with some MAF sensor cleaner. If that doesn't work than you may need to replace it.

1995 old acheiva hard to stay running when first starting after it warnup it ok


Hi,
Sounds like no gas is getting to the carb. Or it can be a fuel issue. Bad fuel pump or clogged filter can be the reason, it can be solved by replacing the fuel filter and fuel pump fuse..
Failing EGR or PCV valve. Changing the PCV valve; this can affect starting, especially in cold weather and will allow you to start the car, but then it will die. EGR is similar, but affects more than just starting. The PCV tends to be ok after warm-up.
Everything on a car works together: Simple oil change or air filter change, or fuel filter change make a car start better.
Also there could always be a malfunctioning sensor, you can test this with the help of a mechanic or buy buying an OBDII code-checker at a store.

Let us know if you need further clarification else please accept the solution.
Thanks for contacting fixya.com

Replaced fuel pump now wont run right once warm


If it ran normally before changing fuel pump, you probably have a bad aftermarket pump out-of-the-box. Try "thepartsladi" store on eBay for low price OEM.

1994 s10 blazer 4.3 cpi,starts and drives but has miss/stumble right before it shifts,if it gets warm it starts running rough and dies has new fuel pump,fuel filter, cap,rotor,ign moduletranny filter,plugs...


check these two things, the electronic egr valve, located at the front of the engine on top near the front of the intake, they are know for getting something in them and not working properly. also check the cold water temp sensor, located on the driver side of the head.the egr valvce can be taken apart nad cleaned, you might have to get a new gasket for it.

Is there a inursha switch on the 1994 bravada? we bought the truck used and on the way home it died and we cannot restart it. we are trying to remove the fuel tank to replace the fuel pump but the bolts...


NO switch, but there is a relay under the hood just to the passenger side of the brake booster along the firewall. Check the relay and the fuse under the dash, drivers side. Change the fuel filter if you can hear the fuel pump prime the system for the first 3 seconds when the ignition is placed to the run position. The fuel pressure too should be 60psi to 65psi during prime with the engine not running, you should check that at the shredder valve. The good news is the fuel pump on your 94 is less expensive then the 95's and newer. Good luck and hope this helps.

check air flow duct where the throttle valve is . check the pvc valve . make sure it isnt stuck open. check the egr valve . it will stick open stall out motor .use a scanner it will tell you if you got egr valve problems. check fuel pressure. it could be stop up fuel filter bad fuel pump fuel pump relay.your car problem sound like a major vacuum leak . change spark plug and wires if they have not been change in a while. it could idle air control. hook a scanner .it could give you a code.
