cis pressure gauge
 

Has anyone used the "unwired tools pressure gauge", does it help diagnose cis problems, I have same problem as other poster , where I take coil wire off coil , turn engine over 2 seconds, put back on & runs like champ {hot or cold)rest of day.....the temperature & humidity here is different every day, 80 one day 40 the next,looks to me like it would only diagnose whether your wur was working( they have 2 gauges)...49$ & 99$ 1 says @ rest, no 1 has responded so I guess I'll call them , let u know what I find out

I've never used that model, I have one I purchased from JC Whitney years ago when I had a CIS car. YOu really have ot use a fuel pressure gauge to diagnois CIS problems. Otherwise you're just guessing, and that can get expensive real fast.

thanks for reply!
