Have a 97 gmc jimmy highrider, had problems starting since about a week after buying the truck. Recently wouldn't start, tried the obvious, spark, gas, fuses, etc. anyway was told the spider injeciton was bad. tore down no gas in the ports after removing plentum. tried pressure test on schrader valve, when ignition is on reads ten on gauge, when cranked it jumps up to 50 to 55, any way could get it to start once pouring gas done in the throttle body, would start fine for a couple of hours trying it once every so often. once sitting over night, nothing just cranking and not starting. was also told the regulator in the top of the injectors might be bad, I'm thinking fuel pump, any suggestions anybody?
