The 1995 350 is a "Vortec 5.7" motor if I remember correctly.You will have to get a throttle body and intake manifold for an older 5.7 liter(early 90's?).The Vortec engines are a sequential multiport injection setup(totally different).
firing order for 5.7 v8 is 1-8-4-3-6-5-7-2 mostly all of the chevy v8s are the same firing order. the rotor button in distributer turns clockwise, the cylinder numbers are 1-3-5-7 on drivers side, 2-4-6-8 is on passengers side. To get started get your distrutor cap[new one] look on the top you will see a #1that's where you begin you must know if if rotates clockwise or counter clockwise start in that direction then follow the firing order and cylinder line up. good-day!! if cap is not marked, just pull out #1 plug, put a straw or similar in plug hole on top of piston. turn engine over by crank in front of vehicle with a wrench, when the piston comes to the very top just before it starts going down. this is tdc. and rotor button should be pointing to #1 wire on dist, cap. follow from there. good-day !!
The vortec engine has a time delay fuel pump relay, check that...Was your pressure reading with engine running? Test your injectors. Check the coolant temp sensor, it will confuse the ECM if it is out of range...mainly when the engine is cool. Check the ignition for weak spark, coil resistance. Check the air flow sensor....I would stop using starting fluid immediately, the volatile conditions it creates could cause damage. Hope this helps.
unplug distributor! find #1 cylinder, take out spark plug,placr finger over spark plug hole,bump starter until compression blows finger from spark plug hole,align mark on harmonic balancer with 0 mark on timing cover. engine is on compression stroke.install distributor with rotor contact pointing toward #1 wire location on distributor cap. install plug. install wire. engine will start.
