RENAULT TRAFIC 1900.51 PLATE?

PEOPLE-VERY FRUSTRATED JUST NOW
MY TRAFIC VAN HAS HAD STARTING PROBLEMS THESE PAST 2 WKS TURN IT OVER BUT IT WON'T FIRE.
SPRAYED EASI-START UP AIR FILTER CHANNEL AND WOOOOF OFF SHE WENT.....TO THE GARAGE!
MECHANIC HAS HAD E.C.U. SENT AWAY AND,SO THEY SAY IT'S FINE.
BUT ON STARTING HER TONIGHT THE GLO-PLUG LIGHT STAYED ON-THEN OFF-THEN ON AND SHE MISSED AND SEEMED UNDER POWERED AS WELL. STOPPED HER AND BLED FUEL FILTER.
BUT NO CHANGE
HAS ANYONE GOT ANY IDEAS?
YOURS HOPING FOR A REPLY
