A vehicle of that age lines should probably be all replaced and all rubber hoses checked carefully
Start by checking the fuses.
it is a 1995 Chevy blazer and it will not go into park. have to use the emergency brake when stopped, and neutral to start it
Push it off the wharf would be a good start.
With engine off--pump brake until all vacuum is exhausted With foot on brake start vehicle--brake pedal should drop
Start with checking the bulbs andthe fuse.
You have a small "EVAP" leak. Start with replacing the fuel cap.
put the parking brake on the first click. it wont engage the brake but will turn of the lights but if you have a stock radio it will start beeping at you as soon as you hit about 10mph
Start with checking the left rear brake light bulb.
Start with an inspection and adjustment of the parking brake shoes by removing the rear brake rotors. If the brake shoes are good and they are adjusted up and you still need more adjustment, make final adjustments on the brake cables under the drivers side of the vehicle.
First of all, the size of the motorhome has absolutely nothing to do with how to repair the engine. Specify which make of engine it is, and you may get better results. Tgzzzz: I don't understand how someone could write the above incredibly ignorant comment. If you don't know what a 454 is, stop talking and start listening! Hi! I have a 1984 motorhome (31' ;-) with a Chevy P30-series chassis, 454 engine. The timing is on the air filter cover and is listed as 4 deg. BTDC. I tried looking this up online for myself--the Chevy-published info for this chassis & engine didn't indicate a timing, and directed me to look other than where the timing info _was_ located--and I haven't found it (and I've found a lot of red herrings). You might start w/4 deg., but perhaps a "history of the 454" would indicate model changes which might help with whether or not what I'm seeing would be of use to you.
my 1958 Chevy will not start sometimes
Start with checking the fuses and bulbs. See sources and related links below for bulb information.
