I purchased a used 2000 Chevy Cavilier about 2 months ago and noticed a couple of issues that I am trying to troubleshoot/repair. - One being the speedometer, when i am driving the speedometer goes up and down like crazy especially when I am 40+ in speed? - Front end noise, I had two estimates done and one of the shops said it was the motor mounts. The second shop I went to did an inspection and said the motor mounts looked fine and diagnosed the problem coming from the struts. Now would it be a good idea to pick up some used struts from the junkyard? or buy new? I am leaning more to what the second shop told me because if it was the motor mounts my motor would be shaking (which it doesn't) What is happening is whenever I press on my brakes it makes a clunk, and also when I come to a complete stop and then accelerate it makes that same clunk noise. - Third the fan is making a louder than normal noise when I go to turn it on, but seems to be working fine as far as blowing out hot and cold air ? Overall the vehicle is clean dent free runs strong with no leaks has 76,000 miles. Any advice would be greatly appreciated.

I have a 1991 Dodge caravan 4 cyl. 2.5. Total stop. No warning! Such as an engine missing or flooding or etc... No spark and fuel pump does not operate. Tried new coil, pickup assembly, distributor veins are excellent, new asd relay, and put gas down the throttle. Will not spit. Turns over perfect. No trouble codes. I put a test light in where the ASD inserts. The light lights in one slot when key is off; then lights in two slots when key is on. Therefore, getting power to the ASD. What is there left to do??? If it would be the computer, then how can I be sure that it is the computer?? Very hard to find a computer and very expensive. Hope I can get some answers. Thanks
