Engine shakes hard and wont stay running

[rigs50]

i just recently put my tranny back in with new clutch flywheel etc. and i also did the basic step 1 tunin(egr block off, cap vaccuums etc.) when i try to start the car the engine rocks really hard. and it starts for a few seconds but runs rough then shuts off. could this somehow be timing or just shaking bad because its on stands????? im gonna try changing the plugs but im stumped.

MAS connected?

at first it wasnt but then i plugged it back in and it still did the same thing

touch the timing components at all, could you be of a tooth or two?

Check the firing order on the plug wires too.

my plug wires are cut to certain lengths so they should be right but just in case could you tell me how they should be coming off the coils. i didnt mess with any timing things i just really cleaned some stuff up built egr block off and blocked some vacuum lines.

 

[Mr Peepers]

Double check what you were supposed to block off and any vacuum leaks.

Double check your timing just for the hell of it. It doesnt take long and it will eliminate it as a possibility.

the two timing marks on my cam gears are in the same position. like when one notch is a t 1 o clock so is the other one. is that right i thought they were supposed to match up when the rotate to the middle. the thing is i havent messed with the timing and am not real sure how to fix it. also a few months ago i had the crank-position sensor replaced and at first the plug was on top but now its on bottom. the car ran fine but now i did these adjustments and it is acting up

Intake should be at 9 o'clock and it meet the exhaust which is at 3 o'clock.

How bad does it shake, could be really bad motor mounts causing the shake.

i had idle problems but they got better once the motor mounts and the timing belt were replaced.
