You need to relieve the fuel pressure, Gain access to the fuel rail, should be 4 or 5 bolts holding the fuel rail on... once you accessed and removed the fasteners, carefully pull up on the railon aboth sides.. a little wd may help release the injector seals, and you definitely wanna replace the lower o-rings... be careful liining the injectors up when u install the rail

Hi, I see you have changed a bunch of items, but do we know if the engine is getting fuel pressure? (55 psi at test port), or getting good spark? Could the spark plugs be fouled?I think before you replace too many items, you should start with basics. Good luck, Thanks...

THE 91 NISSAN STANZA idlesreal good but when you press the gas it goes fast then slow then fast and slow again will not run smooth

could be clogged fuel injectors, fuel pump, fuel filter first what I would do is clean fuel injectors and replace fuel filter, if there is no codes, meaning your check engine light is not on, some times bad gas can do this or water in gas, better to try the easy things first, plus they real dont cost.much, now I use Lucas fuel injector cleaner myself, I have always got good response from it, plus if need to, you can put a tube in every day, thats if you use about 10 gallons of gas everyday so.try this first, cost for Lucas is around $6 also change fuel filter, cost any where from $7 to $25

I think my fuel injectors need cleaning or one may be failing is there away to clean them myself other than putting fuel injector cleaner in there anyway to tell if one is failing also is there

No, you cannot clean furl injectors. Fuel today contains cleaners and 99.9% of injector failure is due to an injector whose electrical winding create no or low voltage or high voltage. Either way the faulty injector will cause the engine to miss or run poorly. You can use a volt meter to check voltage. With the volt meter touch each probe to either terminal on the injector. A normal ohm reading would range from 11.8 -12.9 ohms. Any reading from 1.0 to 8.0 or 15.0 and higher, the injector is no good and should be replaced.

99 Astro van. This engine has a supply and return line from the injectors. Is it possible to flush the system by plugging the return line and running a can of injector flush through the system myself...

You may further cause problems. I would recommend disconnecting the fuel line at the injectors, and disconnecting the fuel line before the gas tank, making sure there isn't a fuel filter along the way. If there is, then disconnect the fuel line at the filter. Use a compressor and blow air from the injector side, down to the filter end. Make sure you try and keep as much moisture out of the line as possible. You can do this with each segment of fuel line to flush out any particles that may have clogged your lines. Your filter may be your main problem. Try changing that first!
